Extensive use and environmental persistence of tetracycline hydrochloride (TC•HCl) pose significant threats to both ecological environment and human health. It is crucial to explore the efficient degradation method to realize sustainable development. This work proposes a photothermal catalysis (PTC) strategy for the degradation TC•HCl to improve its degradation efficiency than photocatalysis (PC) and thermal catalysis (TC). Porous nanorod-shaped zinc ferrite (ZF) with ferrimagnetic behavior was prepared via a hydrothermal-calcination method. ZF calcined at 400 °C (ZF-400) possesses a typical mesoporous structure with a specific surface area (SSA) of 35.68 m 2 ⋅g −1 , which is 1.97 and 5.03 times higher than those of ZF calcined at 500 °C (ZF-500) and 600 °C (ZF-600), respectively, exhibiting the strong physical adsorption capacity for TC•HCl. Abundant Lewis acid sites on the ZF-400 are beneficial to the chemisorption of TC•HCl. The excellent adsorption capacity of ZF-400 for TC•HCl follows the pseudo-second-order kinetic model with the adsorption rate constant of 61.2 × 10 −3 g⋅mg −1 ⋅min −1 . The PTC degradation of TC•HCl over ZF-400 reaches 93.4 % within 120 min and follows the pseudo-first-order kinetic model with the degradation rate constant of 9.5 × 10 −3 min −1 , being 2.88 times and 1.98 times higher than those of PC and TC, severally. Radical quenching experiments confirm that •O 2− , h + , and •OH serve as the dominant active species in the PTC degradation of TC•HCl over ZF-400. Besides, the PTC degradation of TC•HCl remains above 83 % with no significant decrease in catalyst activity after six cycles.

Silk fibroin hydrogels offer attractive biocompatibility and optical clarity but suffer from water-induced fragility, freezing, and biofouling. Here, regenerated silk networks are enzymatically cross-linked and subsequently exchanged with choline-chloride deep eutectic solvents (DESs) containing glycerol and ethylene glycol to create transparent, ionically conductive SF-DES gels. DES infusion preserves the protein’s β-sheet framework while generating a more homogeneous nanonetwork and denser microstructure, increasing compressive modulus by up to 70% without altering protein concentration. The low volatility and depressed freezing points of DESs impart exceptional durability: the glycerol-based gel loses <5 % mass under 37 °C, RH 35% airflow for 7 days, remains unfrozen at −80°C, and the ethylene glycol-based gel maintains flexibility and conductivity of 0.013 mS cm⁻¹ at −40 °C. Choline-based electrolytes inhibit growth of Escherichia coli and Staphylococcus aureus, mitigating microbial degradation. Leveraging this combination of mechanical resilience, environmental stability, ionic conductivity, and antimicrobial activity, bendable indium-free capacitive touch sensors are fabricated that achieve centimeter-scale position resolution and rapid gesture tracking. The study establishes DES infiltration as a general, aqueous-compatible route to robust, multifunctional protein gels, opening opportunities for sustainable wearable electronics, biomedical interfaces, and extreme-environment sensing.

Preparing the V 3.5+ electrolytes by catalytic reduction of V 2 O 5 with formic acid is a straightforward and efficient process for vanadium flow batteries (VFBs). Nevertheless, converting vanadium ions in a strong acid environment depends on utilizing highly active and stable catalysts. Herein, a novel Pt-based catalyst supported by graphene oxide (GO) and hexadecyl trimethyl ammonium bromide (CTAB) (Pt/GO@CTAB) was developed for the catalytic reduction method. The introduction of CTAB into the catalyst enhanced the dispersion of GO, increased the degree of defects, and created more reduction sites for Pt, thereby improving the catalytic activity for formic acid oxidation. As a result, the reduction rate increased by 42.86 % compared to the Pt/C catalyst. Moreover, an economic analysis of the catalyst revealed that Pt/GO@CTAB could reduce costs by 49.25 %. Finally, charge-discharge experiments were conducted on the VFB single-cell with the prepared V 3.5+ electrolyte, which exhibited comparable Coulombic efficiency (CE) and energy efficiency (EE) to the other electrolytes, with CE and EE values of approximately 97 % and 87 %, respectively. These results suggest that Pt/GO@CTAB is a promising catalyst that not only reduces costs but also maintains electrolyte performance, offering a viable alternative to the traditional Pt/C catalyst for the efficient preparation of vanadium electrolytes.

Nano zerovalent iron (nZVI) has attracted great interest for the heterogeneous Fenton-like catalysis in environmental remediation due to its high capacity and low cost. However, toxicity and pollution risks arising from the rapid chemical corrosion in the oxygenated aqueous medium largely limit its more practical applications. In this study, the two-dimensionally defective MoS 2 was introduced as the key spatial protector to tailor the electron generation, transfer pathway and utilization efficiency of corrosive charge released from the chemical corrosion of nZVI in aqueous medium during reactions. We rationally designed and controllably prepared the nZVI@MoS 2 hybrid, in which MoS 2 spatially encapsulated nZVI to form the core-shell structure. Fenton-like catalysis on nZVI@MoS 2 produced reactive species to decompose refractory pollutants. Inner nZVI core transferred electrons to PMS through outer MoS 2 shell to activate PMS. Moreover, the MoS 2 shell promoted the Fe(II)/Fe(III) redox-cycling on nZVI and slowed down chemical corrosion of metallic core for superior and sustainable catalysis. Quenching and electron paramagnetic resonance tests indicated the involved hydroxyl radical, sulfate radical, superoxide radical and singlet oxygen with good reusability. Our work provided a new strategy to refine the environmental potential of nZVI benchmark with high industrial importance by two-dimensional transition metal sulfides for the superior environmental Fenton-like catalysis.

Deep hydrogenation of polycyclic aromatic hydrocarbons (PAHs) into jet fuel is an important strategy for the upgrading of light cycle oil (LCO). Zeolite-supported metal catalysts have exhibited good catalytic performance for hydrogenation of PAHs under relatively mild conditions. However, the impacts of acidity variations in zeolite supports, arising from the differences in framework Al (Al F ) distribution on the catalytic behavior of zeolite-supported metal catalysts in the deep hydrogenation of PAHs remains unclear. Herein, two series of mesoporous ZSM-5 samples, that is ZSM-5-E- x and ZSM-5-F- x , with the differences in Al F distribution but similar Si/Al ratios, were prepared in the crystallization system with or without NaOH. The results of NH 3 -TPD, Pyridine-IR, N 2 adsorption-desorption and SEM reveal that two series of HZSM-5 samples have similar acid density and acid strength, textural properties, morphology and particle size. However, the results of XPS, 27 Al MAS NMR, 2,6-Ditert-butylpyridine-IR, catalytic cracking of 1,3,5-triisopropylbenzene and the controlled reactions as well as DFT calculation indicate that the higher enrichment degree of Al F on the external surface and the suitable arrangement mode of Al F in ten-membered ring (10-MR) of HZSM-5-F- x compared to HZSM-5-E- x in case of the similar Si/Al ratios, result in Pt/HZSM-5-F- x exhibiting remarkably-improved deep hydrogenation performance of phenanthrene (PHE) compared to Pt/HZSM-5-E- x . Particularly, the selectivity to perhydrophenanthrene (PHP) over Pt/HZSM-5-F-50 can reach above 99.0% at a conversion of PHE (>99.0%). Furthermore, Pt/HZSM-5-F-50 exhibits well reusability. This work helps to clarify the impact of Al F distribution in ZSM-5 on catalytic hydrogenation performance for PAHs, providing valuable guidance for design and development of efficient catalysts for the hydrogenation of PAHs.

Toluene (C 7 H 8 ) is a representative volatile organic compound (VOC) that poses a significant threat to the atmospheric environment and human health. Catalytic oxidation has shown demonstrated advantages in the field of air purification, but precious metal catalysts have significant limitations by their high cost and scarcity. This study used hydrothermal synthesis to prepare manganese dioxide nanowires with a diameter of approximately 100 nm. A multi-scale fiber membrane was constructed with mullite nanofibers, which can effectively remove PM 2.5 and toluene from the air. The filtration efficiency of the composite fiber membrane remaind above 99% at different air flow rates. It can achieve complete oxidation of toluene, and after five cycles of testing, the removal rate of toluene remains at 99.2%, demonstrating good catalytic performance. MnO 2 nanowire/mullite multi-scale fiber membrane has shown great potential for indoor air purifier filters.

The sustainable recovery of valuable metals from end-of-life lithium-ion batteries (LIBs) has become essential for relieving the supply-demand contradiction of key resources. However, the high similarity in physicochemical properties of transition metals poses a fundamental challenge for the selective recycling. Here we proposed a facile strategy for defining the demarcation line of precipitation/dissolution behavior for precise Ni/Co separation. A malonic acid-based deep eutectic solvent (DES) is developed, emphasizing the H 2 O-mediated competitive coordination and differentiated solubility. We discovered the distinctive formation of [Ni(H 2 O) 6 ] 2+ and [CoCl 4 ] 2- in the DES-20 % H 2 O system. Furthermore, the K sp differences of the Ni-complex and Co-complex in the C 3 H 2 O 4 2- -rich environment was effectively magnified. These significant differences synergistically enable the generation of C 3 H 2 NiO 4 ·2H 2 O precipitation (∼ 99.9 % purity), achieving a remarkable Ni/Co separation factor of 125, which guarantees sequential separation of all metals. This universal methodology along with in-depth mechanism understanding provides a guideline toward value-added recovery of LIBs.

Antimony-doped tin dioxide reactive electrochemical membranes (ATO-REMs) exhibit robust catalytic activity, yet their large-scale application is hindered by the laborious multi-step synthesis of the conventional sol-gel method. Herein, we propose a facile electrodeposition strategy for fabricating ATO-REMs, involving sequential deposition of Sb and Sn on porous Ti substrates followed by thermal annealing. This method achieved uniform distribution of interconnected ATO clusters with low charge transfer resistance and high electrocatalytic activity. Through systematic analysis of experimental conditions and electrodeposition processes, a comprehensive mechanistic framework was established to elucidate how operating conditions and synthesis parameters influence electrocatalytic performance. By tuning the electrodeposition process, the optimized electrodeposited ATO-REM (EPATO-REM) achieved 99.1% removal of sulfamethoxazole (SMX) during single-pass filtration with a low energy consumption of 0.5 kWh m −3 , outperforming the conventional sol-gel-derived ATO-REM. Further investigations revealed that SMX degradation was driven by •OH oxidation and direct electron transfer, with seven intermediates identified and degradation pathways proposed. Furthermore, EPATO-REMs exhibited oxidation stability during 8-h operation, universal efficacy for diverse contaminants, and practical applicability in complex water matrices. This work provides a facile and scalable alternative to the labor-intensive sol-gel method for ATO-REM fabrication, advancing the development of high-performance REMs for water treatment.

The rapid development of microelectronic devices has increased the demand for miniature energy storage systems that are highly safe and exhibit long cycling life and excellent energy density. However, the lack of low-cost and high-performance fabrication methods presents a significant challenge to thin-film electrode fabrication. This study reports a strategy combining controllable pre-curing treatment with rapid thermal annealing (RTA), which enables in situ fabrication of high-quality sodium vanadium phosphate [Na 3 V 2 (PO 4 ) 3 ] thin films. RTA facilitates the cleavage of weak metal–O bonds in the precursor film, whereas optimisation of the pre-curing duration (0–100 s) effectively eliminates organic residues and strengthens the carbon framework, suppressing particle agglomeration. This synergistic control substantially improves crystallization uniformity and film densification, resulting in a refined grain structure and highly oriented crystal facets. Under optimal conditions, the thin film demonstrates a high specific capacity of 85.6 mAh g −1 at a current density of 1 A g −1 , retains 72.5 mAh g −1 even at 20 A g −1 , and demonstrates 90.3 % capacity retention after 200 cycles. Moreover, the assembled full sodium-ion cell exhibits an average operating voltage of 1.3 V while maintaining 94.2 % capacity retention after 500 cycles. This study elucidates for the first time the synergistic regulation pathway of the pre-curing–RTA coupling mechanism in Na 3 V 2 (PO 4 ) 3 thin-film fabrication and proposes an advanced preparation strategy for cost-effective, highly integrated, high-power sodium-ion thin-film devices, providing critical theoretical foundations and robust technical support for next-generation all–solid state sodium microbattery design and development.

N -cyclohexylcyclohexanimine (N-CCA), a by-product of cyclohexylamine (CHA) oxidation to cyclohexanone oxime (CHO), was used as the starting reactant for the efficient conversion to CHO under an oxygen atmosphere, utilizing the constructed surface hydroxyl-rich Ti-based catalysts. Of these, the 20% TiO 2 /Hβ catalyst exhibited unique catalytic activity and stability, achieving 45.9% N-CCA conversion and 82.1% CHO selectivity, with the content of high-boiling by-products not exceeding 1.0%. The superior catalytic performance, as evidenced by characterization results, stems primarily from: (i) the combination of TiO 2 and Hβ, which promotes the formation of a high specific surface area with fine TiO 2 nanoparticles and high-density Ti δ+ active sites, which facilitate the adsorption and activation of N-CCA; (ii) the construction of rich hydroxyl groups, which enhances the Brønsted acid sites, thereby improving the generation of active oxygen species; (iii) the intercrystalline embedding of TiO 2 and Hβ, which forms Ti–O–Si bonds, effectively inhibiting Ti leaching and ensuring excellent catalyst stability. The conversion of N-CCA, the main by-product of CHA oxidation, to the desired CHO using an efficient and robust 20% TiO 2 /Hβ catalyst represents an attractive pathway.

A novel lanthanum-modified biorefinery residue of wheat straw (La-BRWS) was synthesized, characterized, and applied for the removal of phosphate from aqueous solution. Characterization analyses confirmed the successful incorporation of lanthanum, which significantly enhanced the material’s adsorption performance. The results demonstrated that La-BRWS possessed a large specific surface area, a porous structure, and excellent stability across a wide initial pH range (1.01–10.83). Phosphate adsorption kinetics on La-BRWS were effectively described by both pseudo-first-order and pseudo-second-order models. The Langmuir isotherm model provided the best fit for the equilibrium data, indicating a maximum adsorption capacity of 55.74 mg P/g at 50 °C. The adsorption process was endothermic and spontaneous, reaching rapid equilibrium within 20 min, and demonstrated excellent stability in the presence of co-existing ions (Cl − , NO 3 − , HCO 3 − , and SO 4 2− ). Regeneration with 5 M NaOH retained over 99% of the adsorption capacity after five cycles. The phosphate adsorption mechanism involved ligand exchange, precipitation, and Lewis acid–base interaction. This study proposes La-BRWS as an economical and effective phosphate adsorbent derived from biorefinery residue of wheat straw, and provides new insights for reducing the cost of biorefinery.

Tunable electromagnetic wave responses are increasingly attracting attention in the realm of integrated electronics. However, the modulation flexibility and reliability are limited in the current electromagnetic shielding materials. In this study, a device with a sandwich-structured configuration of metal mesh@H x WO 3 /H 2 SO 4 /hollow graphite is designed to enable dynamic response and precise control for electromagnetic waves (EMWs). In-situ characterizations and theoretical simulation revealed that the electrochemically controlled cation intercalation preferentially triggers the reversible conversion of H x WO 3 from the monoclinic phase (M-phase) to the tetragonal phase (T-phase), and subsequently to the cubic phase (C-phase) by voltage management, which leads to a successive increase in valence electrons and enhancement in conductivity for precisely modulating reflection shielding efficiency of the incident EMWs. Furthermore, the intercalation and accumulation of the external cations produce a mass of dipoles in the crystal H x WO 3 host structure, which further enhances the dielectric performances of materials and the dissipation capability of incident EMWs, and thus improves the electromagnetic absorption shielding effectiveness. Consequently, the outstanding modulation capability Δ: 42.36 dB) and consecutively tunable intensity (from 10.98 to 53.34 dB) of electromagnetic shielding effectiveness is realized, which provides a more remarkable technology for adapting to demanding environments through the dynamical regulation of EMWs.
