Abstract Solar-driven photocatalytic CO2 conversion into value-added chemicals and fuels is an emerging solution to the challenges of traditional energy environmental/climate concerns. However, synthesis two-carbon (C2) compounds quite challenging due high activation barrier C-C coupling reaction low content intermediates. Herein, inspired by tandem in multi-enzyme reactions, Cu-N4 Mo-N4 active sites have been designed integrated CuPor-POP-Mo as cascade dual metal for efficient reduction ethane (C2H6) first time. Significantly, excel-lent C2H6 production rate 472.5 µmol g− 1 h− a product selectivity 87.5% (electron ~ 97.5%) achieved, which are record values using porous polymer catalysts. In-situ spectral characterizations DFT calculations indicate that unlike electrocatalytic C2 products reported previously, Cu site mainly catalyzes *CO production, Mo triggers between intermediates, thus synergistically boost photoreduction C2H6. Our work provides new insights rational design photocatalysts effective C2+ from CO2.

Zerovalent iron (ZVI) is a widely utilized remediation agent for contaminated soil and groundwater; however, it has consistently faced the challenge of balancing catalytic activity with storage stability. Herein, submicron ZVI particles were phosphatized to produce (P-ZVI), which was employed activate peroxydisulfate (PDS) phenol degradation. As anticipated, phosphatization significantly enhanced both stability (>10 months vs 1 d) (4.37 0.12 L m–2 h–1) compared unphosphatized counterparts attributed formation crystalline Fe3P shell on P-ZVI. This selectively interacts H2O/O2/PDS, maintaining P-ZVI under high humidity oxygen conditions while creating mass transfer channels that enhance reactivity in presence PDS. Characterization results from reaction process demonstrated activated PDS through direct (via Fe cations) indirect pathways (through phosphorus anion-mediated Fe3+/Fe2+ cycle), generating reactive species facilitating between core Fe0 external efficient activation study elucidates how constructing an can realize selective simultaneously enhancing stabilities ZVI, thereby boosting practical application PDS-based advanced oxidation processes various environmental remediation.

Frequent use of pesticides results in the release large quantities their residues environment, raising various concerns for humans and ecosystem. This work introduces a simple cost-effective method removal atrazine pesticide residue (APR) from agricultural wastewater using Cu doped-ZnO photocatalyst (Cu-ZnO). The modification ZnO with significantly improved its optical photoelectrochemical properties, band gap narrowing 3.3 to 2.64 eV. photodegradation APR was 93.6 91.7% aqueous solution wastewater, respectively. After being reused four times, Cu-ZnO did not display notable drop degradation performance, rates 93.6, 91.2, 86.8, 83.1% during first, second, third, fourth recycles, Also, after six cycles <2%, suggesting excellent stability modified without any issues related secondary pollution. Under natural sunlight, 83.9% removed, confirming benefit reducing treatment costs by utilizing renewable energy. In addition, mechanism proposed based on outcomes radical quenching TOC tests.
