Zinc ion capacitors (ZICs) based on a carbon cathode represent new generation energy storage system, owing to outstanding safety, economic viability, and ecological sustainability. However, carbon-based cathodes suffer from limited charge storage. Thus, it is urgent to develop advanced carbon materials with a large available specific surface area and abundant active sites to boost the storage capacity of zinc ions. Herein, the lignin-assisted K2CO3 activation strategy is reported for constructing N/S co-doped hierarchical porous carbon frameworks (PCSs) using coal tar pitch as the primary carbon precursor. The pore-forming effect of K2CO3 coupled with the skeletal support of lignin promotes pyrolytic cross-linking of the precursor to form a porous nanosheet morphology. Meanwhile, N/S co-doping effectively modulates the electronic structure and produces additional active sites on the surface of PCSs. Besides, the reversible chemisorption/desorption of Zn2+ with O-containing groups occurring on PCSs has been monitored via in situ infrared spectroscopy, which provides additional pseudocapacitance. Consequently, the constructed ZICs with the PCS4 cathode can achieve a capacity of 125.31 mAh g-1 at 0.1 A g-1 and an energy density up to 96.43 Wh kg-1.

Genotypic recalcitrance limits efficient somatic embryogenesis (SE). In this study, an SE induction system for the recalcitrant species Lilium amabile Palib. was established by modulating redox homeostasis. The first SE in this species was achieved by supplementing MS medium containing 1.0 mg·L −1 picloram (PIC) with 150.0 mg·L −1 glutathione (GSH), which increased SE induction rate from 0 to 33.3%. Physiological analysis revealed that GSH treatment upregulated endogenous GSH and key antioxidant enzymes, glutathione peroxidase (GPX) and glutathione S-transferase (GST). Specifically, their activities were elevated 1.9- and 9.8-fold higher, respectively, than those of control. This synergistic action scavenged hydrogen peroxide (H₂O₂), thereby alleviating oxidative stress. Furthermore, LaGSTU6 was identified as a core regulator of SE. In the SE-efficient lily Lilium martagon var. pilosiusculum Freyn, transient silencing of LaGSTU6 delayed embryogenesis initiation, caused severe browning, induced H₂O₂ accumulation, and reduced the antioxidant capacity, yielding a significant decrease in both the SE induction rate and efficiency. These findings preliminarily confirm that LaGSTU6 is a critical regulator of SE competence in lilies. Thus, we overcame genotypic recalcitrance and established the first SE induction system in Lilium amabile Palib. Our findings provide insights into the study of totipotency and inform strategies for regenerating recalcitrant germplasms.

Dual-role ILs act as solvent and PTC for efficient aromatic O,S-glycosidations. • Multilevel screening and experimental validation identify the optimal IL. • Screened optimal IL achieves superior performance with various acceptors. • Mechanism analysis reveals the intensification mechanism.Provide a general strategy for screening ILs in aromatic O,S-glycosidations. Aromatic O,S-glycosidations between (thio)phenols and glycosyl halides are valuable for synthesizing aromatic O,S-glycosides but often limited by immiscible reactants. This work presents a reaction intensification strategy for efficient O,S-glycosidations by using dual-role ionic liquids (ILs) that act as solvent and phase transfer catalyst (PTC). Taking the reaction between 4-nitrophenol and 2,3,4,6-tetra-O-acetyl-α-D-galactopyranosyl bromide to form p-nitrophenyl-2,3,4,6-tetra-O-acetyl-beta-D-galactopyranoside as an example, multilevel computational screening, experimental validation, and comprehensive mechanistic analysis are performed to identify the optimal dual-role IL and understand the explicit intensification mechanism. Specifically, 11,890 IL candidates are first screened as solvents via solubility indicators and physical properties. The easiness of formation and hydrophobicity of ion pairs transferring the liquid–liquid interface are considered to screen ILs as PTCs. After these, 36 potential ILs are filtered out. Considering the availability, 1-octyl-3-methyl-imidazolium tetrafluoroborate is eventually tested via experiment and achieves the best performance. Compared with the basecase IL reported previously, the yield is improved from 34.2 % to 53 %. Meanwhile, this IL exhibits far more superior catalytic efficiency with different acceptors. The acceptors involved are common phenols (i.e., 4-nitrophenol, phenol and p-Cresol) and thiophenols (i.e., 4-methylbenzenethiol, 4-nitrobenzenethiol), which corresponds to O- and S-bridge products, respectively. Mechanism analyses reveal that the reaction is mainly intensified through the extraction effect of ion pair led by the IL, which promotes ion pair transfer from aqueous phase to IL phase and thus leads to better contacts of reactants and catalytic efficiency. Clearly, this work offers useful guidance to screen dual-role ILs as solvent and PTC for efficient aromatic O,S-glycosidations.

Activation of Inert Mg Sites for 2e − ORR Electrocatalysis The π-π interaction between hydroxyl-functionalized carbon nanotubes and Mg phthalocyanine induces an electron-rich structure in the Mg center, optimizing and strengthening the adsorption of ORR intermediates on Mg center, thereby significantly enhancing their 2e − ORR activity and selectivity. Meanwhile, the naturally stable valence state and weak hydrogen adsorption capability of Mg ensure that the catalyst maintains steady 2e − ORR performance at high current densities and H 2 O 2 concentrations, preventing the Fenton reaction from converting H 2 O 2 into hydroxyl radicals (·OH). This effectively ensures industrial-grade H 2 O 2 production with high concentration, current density, and selectivity. • Efficient H 2 O 2 Synthesis and High Economic Viability in Neutral Conditions In a flow cell system, the MgPc/CNT-OH catalyst achieves a Faradaic efficiency (FE) of over 90% at a current density of 500 mA cm −2 . Operating at 400 mA cm −2 , the catalyst sustains stable performance for 50 h with FE of above 90%. Techno-economic analysis reveals that the production cost is significantly lower than the market price at electricity prices ranging from 3 to 9 cents/kWh, confirming its economic feasibility for industrial-scale production. • Ampere-Level Current Electrosynthesis, High-Concentration Product, and Diverse Practical Applications The MgPc/CNT-OH catalyst maintains an FE of over 80% when operating at currents ranging from 0.5 to 20 A in a 100 cm 2 flow cell system. Following a 25-h stability test at 10 A, the catalyst maintained an FE of 85.9% with a H 2 O 2 concentration of 1.82 wt%. By adjusting the flow rate, the electrosynthesized H 2 O 2 concentration reached 8.17 wt%, outperforming currently reported catalysts. The synthesized 8.17 wt% H 2 O 2 was directly extracted into solid sodium percarbonate with virtually no impurities. Antibacterial experiments further demonstrated its potential for diverse applications. Through a molecular modulation strategy, this work achieves significant progress in the efficient electrochemical synthesis of H 2 O 2 with high concentration and selectivity, holding clear implications for sustainable green electrochemistry and environmental fields. We believe these findings will be of great interest to the broad readership of Chemical Engineering Journal and fall well within its scope covering chemical synthesis and electrocatalysis. Below I list some of the representative works published in top-tier journals for comparison. The two-electron oxygen reduction reaction (2e − ORR) emerges as a sustainable route for on-site hydrogen peroxide (H 2 O 2 ) production, and the industrial electrosynthesis of high-concentration H 2 O 2 holds tremendous practical and application value. However, conventional transition-metal catalysts suffer from a critical limitation in the 2e − ORR process, where maintaining high H 2 O 2 selectivity under high H 2 O 2 concentrations remains a formidable challenge. Specifically, under high current densities with low reduction potentials, typical transition metals with variable valence states readily induce Fenton reactions, competitive 4e − ORR, and hydrogen evolution reactions, restricting high-concentration H 2 O 2 generation. To address these, we report a single-site s -block main-group metal electrocatalyst consisting of magnesium phthalocyanine supported on hydroxyl-functionalized carbon nanotubes (MgPc/CNT-OH). The s -block Mg center possesses stable valence and weak hydrogen adsorption, inhibiting Fenton and hydrogen evolution, while the hydroxyl species on the carbon support interacts electronically with Mg sites and optimizes ORR intermediate adsorption. Accordingly, the catalyst delivers ~90% Faradaic efficiency at 400 mA cm −2 . In a 100 cm 2 flow cell, it operates stably for 25 h at 10 A, producing 1.82 wt% H 2 O 2 , which can be increased to 8.17 wt% by adjusting electrolyte flow rates. Techno-economic analysis verifies the superior cost-competitiveness of this system over commercial H 2 O 2 production. Hydroxylated carbon nanotubes optimize the adsorption energy between the phthalocyanine-centered Mg sites and *OOH intermediates, thereby promoting highly selective and active hydrogen peroxide production. Meanwhile, the s -block metal sites effectively suppress the competing hydrogen evolution reaction (HER) and Fenton reactions.

A facile one-pot strategy was developed to construct a core-shell UMOP-S-2-Ppa@SiO 2 composite using (S)-2-phenylpropionic acid as chiral selector. The prepared UMOP-S-2-Ppa@SiO 2 composite was utilized as a novel chiral stationary phase (CSP) for HPLC enantioseparation. Under normal-phase HPLC conditions, the packed column afforded effective enantioseparation for 18 racemates including alcohols, aldehydes, esters, ketones, amines, and epoxy compounds, among which 11 pairs of enantiomers achieved baseline resolution. Compared with the widely used Chiralpak AD-H and Chiralcel OD-H columns, the developed chiral column exhibited good chiral separation complementarity. It can efficiently resolve some racemates that fail to be separated by the above commercial columns. The column also demonstrated satisfactory repeatability and stability, and the relative standard deviations of retention time and peak area remained below 1.0% after 250 consecutive injections. These results demonstrate that chiral metal-organic cages(MOC)@SiO 2 core-shell composites prepared via a post-synthetic modification strategy hold great promise for HPLC enantioseparation, offering new insights into the development of MOC-based materials for chromatographic applications.

Exploring highly active, cost-effective, and long-life non-precious metal-based catalysts for the oxygen reduction/evolution reaction (ORR/OER) is extremely important for renewable energy conversion devices. Herein, a facile approach is proposed to fabricate a FeNi nanoparticles decorated 3D N, S, F tri-doped porous carbon nanoflower/nanotubes electrocatalyst (FeNi@NSFC) by a self-assembly pyrolysis process. The ammonium sulfate not only acts as a N and S source but also facilitates the self-assembly of 2D ZnFeNi-ZIF nanosheets into 3D nanoflowers. Meanwhile, the potassium fluoride serves as a F source and regulates the crystal growth as well as pore structure. The 3D nanoflower/nanotube structure benefits the exposure of reactive species and mass/charge transport. The optimized FeNi@NSFC catalyst achieved outstanding bifunctional catalytic performance with an overpotential gap (0.655 V), which was lower than the Pt/C + RuO 2 catalyst (0.670 V). Theoretical findings also revealed that the introduction of N, S and F atoms could tailor the electronic structure of FeNi nanoparticles, thereby enhancing the catalytic activity for ORR. Therefore, the FeNi@NSFC-assembled Zinc-air batteries (ZABs) delivered a peak power density (156.2 mW cm −2 ), and long-term cycle durability (550 h), surpassing Pt/C + RuO 2 -assembled ZABs. This work demonstrates a promising avenue for developing MOF-derived catalysts with well-defined morphology and multi-atom doping.

To solve the problems of narrow light absorption range and relatively fast photogenerated carrier recombination of traditional photocatalysts, this paper synthesizes a new core-shell polydopamine/bismuth phosphate (PDA/BiPO 4 ) composite material, which has an S-scheme heterojunction structure. The two – step solvothermal method is adopted, and then in-situ self-polymerization of dopamine is carried out. Adding polydopamine (PDA) not only broadens the light response range of the material but also greatly improves photothermal conversion efficiency. The experimental results demonstrated that the optimized 10% PDA/BiPO 4 composite achieved a degradation efficiency of 92% for Methylene Blue (MB) in 150 min under simulated solar irradiation. The kinetic rate constant (0.01612 min −1 ) was approximately 7 times that of pure BiPO 4 . The wide light absorption of PDA and the S-scheme heterojunction make the composite material have excellent photothermal properties, and the surface temperature rises to 108.3 °C within 120 s. Mechanism analysis shows that the S-scheme charge transfer pathway suppresses the recombination of electron-hole pairs, and the synergistic photothermal effect accelerates the interface catalysis. This study provides a multifunctional strategy integrating enhanced light absorption, efficient charge separation, and photothermal conversion, and provides new insights for designing high-performance full-spectrum responsive photocatalysts.

A metal-free sulfur-doped nitrogen-rich carbon nitride (S-C 3 N 5 ) photocatalyst was constructed to promote directional photogenerated charge migration for enhanced hydrogen peroxide (H 2 O 2 ) production and explored the potential for environmental remediation. Physicochemical properties of S-C 3 N 5 such as the surface morphologies, photoresponse characteristics, and charge separation efficiencies were thoroughly analyzed, meanwhile the performance of H 2 O 2 production was evaluated and its reaction pathway was demonstrated through electrochemical characterization and theoretical simulation calculation. Under simulated sunlight, S‑C 3 N 5 achieves a H 2 O 2 photosynthesis rate of 2784 μmol g -1 h -1 with a 95% selectivity toward 2e - oxygen reduction reaction (ORR), compare with C 3 N 5 . This high performance originates from the introduced S sites, which act as strong electron donors and localized active centers that facilitate O 2 adsorption and activation via an indirect 2e⁻ ORR pathway. This work clarifies the critical role of metal-free heteroatom doping in regulating charge behavior and offers a design strategy for efficient molecular‑oxygen activation in photocatalysis.

Catalytic systems that couple pollutant degradation with hydrogen evolution have attracted significant attention due to their potential to simultaneously address environmental and energy issues. In this study, an S-scheme heterojunction composed of lamellar polymeric carbon nitride (PCN) anchored with a rod-like cerium metal–organic framework (Ce-MOF) was successfully synthesized via a facile one-step oxidation method, enabling efficient visible-light-driven photocatalytic hydrogen evolution and simultaneous tetracycline degradation. The optimized PCN/Ce-MOF composite delivers a hydrogen production rate of 495.7 μmol g−1h−1and achieves a tetracycline removal efficiency of 78%. Such excellent performance is attributed to the charge transfer mechanism of the S-scheme heterojunction in the PCN-Ce-MOF composite during the reaction process, while retaining the intrinsic redox capabilities of both materials. Meanwhile, mechanistic studies reveal that tetracycline can effectively capture holes during its efficient degradation, inhibit electron–hole recombination, and promote proton reduction to generate hydrogen. This investigation provides valuable insights for the rational design of S-scheme heterojunction photocatalysts, aiming to achieve efficient and stable photocatalytic hydrogen production and synergistic degradation of organic pollutants.

Photocatalytic technology based on a heterojunction structure has been demonstrated as an effective approach to address environmental pollution and energy issues. In this study, an oxygen-vacancy (Ov)-rich S-scheme BiVO4/Bi-TCPP heterojunction was fabricated via a facile hydrothermal method for the degradation of tetracycline (TC) and oxytetracycline (OTC), and innovatively applied to wheat seed germination experiments to evaluate the ecological safety of treated water samples. A series of characterization results indicate that the one-step strategy enables the in situ introduction of oxygen vacancies and simultaneous heterojunction construction, avoiding complex post-treatment processes. The oxygen vacancies generate defect sites and electron trapping centers, effectively narrowing the band gap, enhancing visible light absorption capacity, and promoting the separation of photogenerated carriers. The S-scheme heterojunction formed by BiVO4/Bi-TCPP coupling effectively facilitates charge transfer, further promotes carrier separation, and improves photocatalytic activity. Under visible light irradiation, the optimized system achieved a TC degradation rate of 90.15% within 90 min and an OTC degradation rate of 85.30% within 120 min, with excellent stability. In addition, the photocatalytic degradation mechanism and dominant active species of the Ov-rich S-scheme BiVO4/Bi-TCPP heterojunction were investigated. Wheat seed germination experiments confirmed that the phototreated antibiotic wastewater significantly reduced the inhibitory effects on the wheat seed germination rate and root elongation, demonstrating that this system not only efficiently removes antibiotics but also effectively eliminates their ecological toxicity, ensuring the environmental safety of the effluent. This study provides new insights into the Ov-regulated S-scheme photocatalytic degradation of TC and OTC and broadens its potential application in wastewater remediation.

Co-contamination of soils is an increasingly severe environmental issue, requiring rapid, effect-based tools to assess ecological risks in complex soils. In this study, we developed a high-performance magnetic nano-biosensor by assembling biomimetically synthesized Fe 3 O 4 @Mms6 nanoparticles with the marine, luminescent bacterium, Photobacterium phosphoreum ( P. phosphoreum ), and its proof of concept by the toxicity of metal(loid)s mixtures. Fe 3 O 4 @Mms6 exhibited favorable properties for biosensor construction, including a uniform size (16.05 nm), high magnetic responsiveness (74 emu g −1 ), and minimal toxicity to P. phosphoreum. These attributes enabled enhanced luminescence (approximately 2800 mV) and stable magnetic recovery of the assembled biosensor. Compared with free P. phosphoreum , the biosensor showed greater sensitivity, reducing the EC 50 for Hg 2+ -induced luminescence inhibition from 1.29 to 0.93 mg kg −1 and lowering the coefficient of variation (CV) from 13.02% to 8.39%. Dose–response relationships further confirmed sensitivity to Hg 2+ and Zn 2+ . Optimal biosensor performance was achieved at a salinity of 2.98%, pH 7.01, and a soil-to-water ratio of 0.039 g mL −1 with a 30 min incubation. Field application at a coal chemical site revealed a significant correlation between biosensor responses and the comprehensive potential ecological hazard index (HI) (Pearson r 2 = 0.81, p < 0.01). Overall, this study provides a robust and field-applicable approach for assessing the toxic potential of contaminated soils.

The unidirectional electric field derived from the p-n heterojunction accelerates carrier migration. • The S-scheme interfacial charge transfer pathway expedites the separation of electron-hole pairs. • Carrier transfer trends are corroborated by density functional theory calculations. • Demonstrates reliable detection of ornidazole in real-world samples. Ornidazole (ONZ) is a widely used nitroimidazole-class antibiotic whose environmental persistence due to misuse intensifies antimicrobial resistance and accelerates pathogen evolution, posing serious risks to human health and ecological safety. To address this issue, we developed a novel photoelectrochemical (PEC) sensor for ultrasensitive ONZ detection based on a p-n heterojunction between pseudobrookite-type oxide MgTi 2 O 5 and the metal-organic framework (MOF) Cu-BTC. Density functional theory (DFT) calculations corroborate the favorable band structure of the heterojunction. The built-in electric field and S-scheme charge transfer at the interface enable efficient separation of photogenerated carriers, yielding an ultralow detection limit of 0.65 pM, a wide linear range from 1 pM - 10 nM (R 2 = 0.9992), and excellent anti-interference, selectivity, stability and reproducibility. The sensor achieved 98.43% - 103.62% recovery in real samples including commercial capsules, tablets, and environmental water, demonstrating high practical reliability. This work presents a cost-effective, portable, and high-performance platform for ONZ monitoring and offers new insights into advanced PEC sensor design for antibiotic pollution detection.
