Peroxymonosulfate (PMS) activation through non-radical pathways exhibits high efficiency and selectivity for pollutant degradation. However, the complex regulation of catalytic active centers makes the generation of 1 O 2 challenging. In this work, Beta zeolite with uniformly dispersed Al-Ov-Co active sites (Co-Beta zeolite) was synthesized via a simple impregnation method, which exhibits excellent 1 O 2 steady-state generation concentration (2.46 × 10 −11 M) at extremely low doses (0.05 g/L). Compared with the original Co 3 O 4 , Co-Beta zeolite displays significantly enhanced PMS activation efficiency, and the apparent reaction rate constant for degrading tetracycline hydrochloride (CTC) increases by 4.7 times. Pyridine infrared characterization confirms that cobalt ions occupy the Brønsted acid sites of the Beta zeolite and undergo proton exchange with them. Accompanied by the redistribution of electrons during the calcination process, some lattice oxygen in the material is removed to form Al-Ov-Co sites. The proportion of Co 2+ in the Al-Ov-Co sites dramatically increases, thereby ensuring efficient activation of PMS. As PMS is adsorbed onto the Al-Ov-Co sites, the H atom of PMS directly bonds with the O atom in Co-Beta zeolite, while the O atom in PMS forms a bond with Co 2+ . After the H O and S O bonds of PMS are broken, abundant 1 O 2 is produced. In practical application evaluation, Co-Beta zeolite shows satisfactory anti-interference ability, reliable cycling stability and acceptable metal leaching. This work inspires the design of highly-dispersed Co 2+ to promote non-radical pathways for PMS-activated water purification.

The catalytic performance of TS-1 zeolites in selective oxidation reactions is strongly influenced by both the TiO6 concentration and specific surface area. However, simultaneously optimizing these two critical factors remains a significant challenge. Herein, a biuret-assisted hydrothermal synthesis strategy was developed to fabricate hierarchical TS-1 zeolites with high TiO6 concentration and enhanced specific surface area. The interaction between the amide groups of biuret and Ti monomers promoted the formation of TiO6 during crystallization, while the confinement effect of biuret facilitated the construction of mesopores. The resulting hierarchical TS-1 exhibited good catalytic activity and stability towards 1-hexene epoxidation and oxidative desulfurization reactions, where the conversion was 1.41 and 3.36 times higher than that of conventional TS-1, respectively. This work provides a facile approach for designing high-performance TS-1 catalysts by dual regulation of active sites and porosity.

Zinc metal is recognized as a highly promising anode material for aqueous zinc-ion batteries due to its high theoretical capacity and favorable oxidation-reduction potential. Nevertheless, uncontrolled zinc dendrite growth and side reactions pose critical challenges to their practical applications. Herein, the amide groups are introduced into microporous polymers (PIM-CONH 2 , denoted PC) via amine functionalization and applied as a surface engineering coating for zinc anodes. The functionalization of amide groups enhances the zincophilicity of the polymer coating through coordination interactions with Zn 2+ , while also forming hydrogen bonds with water molecules to reduce solvation and prevent side reactions. Additionally, the microporous structure of PIM-CONH 2 facilitates the uniform distribution of Zn 2+ , promoting more even ion flow, enhancing dendrite-free zinc deposition, and improving electrochemical stability. Consequently, the PC@Zn||PC@Zn symmetric battery achieves prolonged cycle stability over 1250 h at 0.5 mA cm −2 /0.5 mAh cm −2 . The PC@Zn||Cu asymmetric battery exhibits stable zinc plating/stripping over 2200 cycles at 2.0 mA cm −2 /1.0 mAh cm −2 and achieves an average CE of 99.8 %, which exhibits exceptional Zn plating/stripping reversibility. The PC@Zn||NVO full battery demonstrates outstanding cycling performance, retaining 72 % specific capacity retention after 2000 cycles at 10 A g −1 . This work establishes a generalizable strategy for high-performance zinc metal anodes through rational design of functional microporous polymer interfaces, opening new avenues for sustainable energy storage systems.

Exploring efficient and durable non-noble metal catalysts toward oxygen reduction/evolution reaction (ORR/OER) is of practical significance in advancing Zn-air batteries. Herein, we introduce a three-dimensional (3D) bifunctional electrocatalyst (Fe/Ni@NSC) consisting of N, S-dual doped mesoporous carbon nanosheets/carbon nanotubes embedded with abundant FeS/FeNi nanoparticles and Fe/Ni-N x sites by integrating rod-like ZIF-L@S-g-C 3 N 4 with Fe/Ni-phen complex and subsequent pyrolysis. The 3D structure not only offers a high surface area for active sites but also accelerates O 2 transport/charge transfer. Leveraging the synergistic effect of the 3D porous carbon network and multiple active sites, Fe/Ni@NSC exhibited outstanding activities in both ORR (half-wave potential, 0.868 V) and OER (overpotential, 317 mV at 10 mA cm −2 ), indicating a low potential gap of 0.679 V, outperforming the Pt/C + RuO 2 benchmarks (0.695 V). The Zn-air batteries based on Fe/Ni@NSC achieved a promising open circuit voltage (1.47 V), peak power density (172.59 mW cm −2 ), as well as long-term cycling stability (370 h). Furthermore, density functional theory (DFT) calculations also demonstrated that the interfacial electronic interaction between FeS and FeNi effectively boosted the bifunctional catalytic performance for ORR/OER. This study lays the foundation for designing low-cost and efficient 3D structure non-noble metal catalysts for more energy conversion and storage devices.

Fenton-like oxidation is often hampered by high energy barriers, uncontrolled oxidation pathways, and inefficient reactive oxygen species (ROS) utilization. Here, we report an energy-driven confined catalytic nanoreactor that leverages the in-situ confinement energy generated within nanopores to fundamentally regulate degradation thermodynamics. Taking sulfamethoxazole (SMX) as a model contaminant, the confined nanoreactor exhibited a 22.11-fold higher kinetic constant (0.157 min −1 ) and 40 % enhanced mineralization efficiency compared with its non-confined system. The imprinting channel of confined nanoreactor enabled selective adsorption of SMX within the nanochannel, inducing pronounced confinement effects. The resulting confinement energy triggered a low-entropy degradation pathway (ΔS reduced by 3.2 × 10 3 -fold), which broke thermal equilibrium constraints and redirected SMX oxidation along a low-energy-barrier route. The in-situ confinement-induced low-entropy reaction not only accelerated pollutant degradation but also improved ROS conversion efficiency. This study demonstrated a green and sustainable approach to overcome the intrinsic efficiency bottleneck of Fenton-like processes and provide a new perspective on exploiting nanoconfinement effects for environmental remediation.

The production of biodiesel from renewable feedstocks through energy-efficient processes remains a pressing challenge. Pickering emulsions, stabilized by solid particles, have emerged as a promising approach to enhance biodiesel production. This study presents the synthesis of dumbbell-shaped Janus polymer nanoparticles (DS-JPNs) functionalized with organic amine bases, which serves as Pickering interfacial catalysts (PICs) for transesterification reaction. The anisotropic morphology and amphiphilic nature of DS-JPNs promote stable adsorption at the soybean oil-methanol interface, leading to reduced interfacial tension, smaller droplet formation, and the generation of thermodynamically stable emulsions. This microreactor system prominently enhances the interfacial area and mass transfer efficiency, thereby accelerating the transesterification efficiency. Consequently, the DS-JPN-TMA catalyst achieved a biodiesel yield of 85.4 % under static conditions, a 2.6-fold increase compared to the spherical PS-TMA counterpart (34.2 %). Among the examined Janus organic base catalysts, DS-JPN-TBD demonstrated the highest catalytic performance (TOF 12.51 h −1 ), attaining a biodiesel yield of 96.7 %, attributable to the strong basicity of its bicyclic guanidine moieties. Furthermore, DS-JPN-TBD retained 94.2 % of its catalytic activity after five reaction cycles, evidencing excellent reusability and durability. This study underscores DS-JPN-TBD as an innovative, energy-efficient, and sustainable solution for biodiesel production and proposes a scalable strategy for green energy applications.

Antibiotics have garnered increasing global concern due to their frequent detection and persistence in the environment, which can lead to ecological risks, biological resistance, posing a potential threat to ecosystem and human health. This study investigated the occurrence of antibiotics in a typical tidal channel located in the lower reaches of the Dongjiang River during both wet and dry seasons. Additionally, high-frequency continuous dynamic monitoring was conducted over a full tidal cycle at a tidal-influenced section. The total concentrations of antibiotics ranged from 11.46 to 940.53 ng/L in the wet season and from 15.08 to 322.31 ng/L in the dry season. Fluoroquinolones, particularly ciprofloxacin, were the predominant antibiotics detected. Concentrations were significantly higher in the wet season compared to the dry season. Spatially, antibiotic levels exhibited a pattern with higher concentrations in the upstream and downstream regions and lower concentrations in the middle section. Furthermore, antibiotic concentrations showed a clear tidal influence, with the lowest levels observed during ebb tide and the highest during flood tide. Ecological risk assessment indicated that antibiotics posed higher ecotoxicological risks in the wet season than in the dry season, with fluoroquinolones representing the highest risk category. The potential for antimicrobial resistance was relatively high for ciprofloxacin, moderate for ofloxacin and norfloxacin, suggesting that these compounds should be prioritized in risk management strategies. In contrast, human health risks associated with antibiotic exposure were found to be negligible. These findings offer valuable insights into the behavior and management of antibiotic pollution in tidal rivers.

Generally, Fe(II) has an efficiently catalytic activity toward peroxymonosulfate (PMS), but the slow conversion of Fe(III) to Fe(II) and production of iron sludge impede the practical application of Fe(II)/PMS system. In this work, ascorbic acid (AA), a complexing agent and reductant, was introduced to Fe(III)/PMS process to facilitate the Fe(III) reduction. The decoloration of rhodamine B (RhB) was obviously enhanced in Fe(III)/PMS process with the addition of AA. Fe(III)-AA complex was firstly generated in Fe(III)/AA/PMS process via the complexation and then was reduced to Fe(II), which could catalyze PMS to yield oxidative species. Fe(IV), sulfate radical (SO 4 •− ) and hydroxyl radical ( • OH) were the working oxidants for RhB decoloration in this system, and SO 4 •− played a major role. Increasing Fe(III), AA or PMS dosage was beneficial to RhB decoloration, but their excessive concentration would hinder RhB decoloration. The existence of HCO 3 − , SO 4 2− or FA in this system showed an inhibition effect on RhB decoloration, while a facilitation effect was obtained when the high concentration of Cl − was present. This research offers a way to improve PMS activation by Fe(III) and a technology for eliminating the refractory organic pollutants from the contaminated water.

Releasing residual stress and reducing interface defects are crucial approaches for improving the photoelectric conversion efficiency and performance stability of perovskite solar cells (PSCs). This research introduces nickel chloride (NiCl 2 ) into the electron transport layer of tin dioxide (SnO 2 ) and applies it to the buried interface of all-inorganic CsPbBr 3 PSCs to prepare carbon-based FTO/SnO 2 -NiCl 2 /CsPbBr 3 /C cell devices. Through the morphological and structure characterization, it is found that introducing nickel chloride facilitates the formation of large and dense perovskite films with residual strain released and the passivation of interface defects. Simultaneously, an analysis of the interfacial energy level structure reveals that optimized energy levels enhance electron-hole separation and transport efficiency while effectively suppressing non-radiative recombination. The open-circuit voltage of the all-inorganic perovskite solar cell base on the SnO 2 -NiCl 2 electron transport layer reaches to 1.591 V, and optimal photoelectric conversion efficiency (PCE) of the solar cell devices has been improved from 8.11 % of the control to 9.33 % with NiCl 2 , and the unencapsulated device V OC long term stability maintained 96.9 % within 30 days under atmospheric environment conditions. This study provides new insights into the design of efficient electron transport layer materials to enhance the photovoltaic and environmental stability of PSCs.

Uranium (U) is essential for the nuclear power industry and plays an important role in decarbonizing the energy supply. However, concern regarding the sustainability of U supply is growing, as conventional U ore reserves are scarce and common mining practices have a notable environmental footprint. Exploring alternative U sources and developing sustainable extraction methods are therefore desired. Here we show a spontaneous U extraction strategy based on droplet falling. Specifically, naturally falling salt-lake water droplets interact with a film of aluminium–fluorinated ethylene propylene–chitosan coated on carbon felt, converting mechanical energy into electricity and driving an in situ electrochemical process for spontaneous U extraction. Electrons released at the solid–liquid interface on a superhydrophobic fluorinated ethylene propylene surface reduce U(VI) adsorbed by chitosan to U(IV), ultimately forming U(VI) precipitates. Field experiments conducted in real salt-lake environments with high salinity confirm the scalability and robustness of droplet U extraction, yielding magnesium uranate (MgU 2 O 7 ) and sodium polyuranate (Na 2 U 7 O 22 ) as the main products. A multistep device reduces the U concentration of salt-lake water from 173 μg l −1 to 34 μg l −1 (extraction efficiency of 80.3%) with minimal extraction of co-existing ions. Overall, this work offers a viable pathway to sustainable U resource extraction.

Development of electrocatalytic reduction of carbonyl compounds for carbon‑carbon (C C) coupling represents an effective pathway to achieve sustainable synthesis of multi‑carbon chemicals. The hydrogen evolution reaction (HER) is considered the most significant competitive process, which could be suppressed by weakening the adsorption of protons on interface or by making protons in the electrolyte inactive through the use of certain additives. However, increasing the coverage of protons and carbonyl molecules are necessary to facilitate the generation of hydrogenation intermediates during C C coupling. To reconcile this contradiction, a Ni-based catalyst for electrocatalytic coupling of formaldehyde has been developed, decorated with phosphate groups around Ni sits. The following enhancement could be achieved: 1) Ni sites enhance the adsorption of formaldehyde on catalyst surface and promote their electroreduction; 2) Phosphate groups near the Ni sites can act as protons affinity sites to prevent their self-coupling. As the result, the adsorbed HCHO and hydrogen can be balanced to facile the formation of intermediate *CH 2 OH during C C coupling. Consequently, the PD-Ni/C@CP catalyst exhibits outstanding performance in the continuous preparation of ethylene glycol, with a production rate of 22 mmol/(L·min) and a Faradaic efficiency exceeding 90%, highlighting its potential for the efficient and sustainable synthesis of other high-value chemicals.

Developing robust methods to discriminate methanol from ethanol is critical for industrial safety and quality control. Herein, we report a novel strategy of two-step solvothermal method to synthesize dual-emission carbon dots ( p -PD CDs) from p -phenylenediamine. The p -PD CDs exhibit unique, solvent-dependent fluorescence: in ethanol, they display a dominant blue emission at 445 nm with a weaker red emission at 598 nm; while in methanol, the blue emission is significantly quenched and red-shifted to 465 nm. This distinct solvatochromic response provides a ratiometric luminescent signal ( I 445 /I 598 ) for highly selective methanol detection in ethanol across two linear ranges (1-60 vol% and 60-100 vol%), achieving a detection limit of 0.38 vol%. Comprehensive characterization using transmission electron microscopy (TEM), femtosecond transient absorption (fs-TA), and ultraviolet photoelectron spectroscopy (UPS) revealed that the emission differences originate from methanol-caused aggregation of p -PD CDs. This aggregation is driven by weaker hydrophobic interactions and stronger hydrogen bonding compared to ethanol, leading to aggregation-caused quenching (ACQ) and an accelerated non-radiative decay pathway for the blue emission, as confirmed by time-resolved and transient absorption spectroscopy. The practical utility was successfully demonstrated by accurately quantifying methanol in industrial ethanol and a commercial cleaner with excellent recovery rates (99.5-101.7%), highlighting its significant potential for real-world application.
