Photocatalytic reduction of CO2 to value-added solar fuels is great significance alleviate the severe environmental and energy crisis. Herein, we report construction a synergistic silver nanoparticle catalyst with adjacent atomic cobalt-silver dual-metal sites on P-doped carbon nitride (Co1Ag(1+n)-PCN) for photocatalytic reduction. The optimized photocatalyst achieves high CO formation rate 46.82 μmol gcat-1 70.1% selectivity in solid-liquid mode without sacrificial agents, which 2.68 2.18-fold compared that exclusive single-atom (Ag1-CN) site (Co1Ag1-PCN) photocatalysts, respectively. closely integrated situ experiments density functional theory calculations unravel electronic metal-support interactions (EMSIs) Ag nanoparticles Ag-N2C2 Co-N6-P promote adsorption CO2* COOH* intermediates form CH4, as well boost enrichment transfer photoexcited electrons. Moreover, atomically dispersed Co-Ag SA serve fast-electron-transfer channel while act electron acceptor enrich separate more photogenerated This work provides general platform delicately design high-performance catalysts highly efficient conversion.

Abstract The shortage and unevenness of fossil energy sources are affecting the development progress human civilization. technology efficiently converting material resources into for utilization storage is attracting attention researchers. Environmentally friendly biomass materials a treasure to drive new‐generation sources. Electrochemical theory used convert chemical substances electrical energy. In recent years, significant has been made in green economical electrocatalysts oxygen reduction reaction (ORR). Although many reviews have reported around application biomass‐derived catalytically active carbon (CAC) catalysts ORR, these only selected single/partial topic (including synthesis preparation from different sources, structural optimization, or performance enhancement methods based on CAC catalysts, CACs) discussion. There no review that systematically addresses latest synthesis, enhancement, applications related CAC‐based synchronously. This fills gap by providing timely comprehensive summary following sections: exposition basic catalytic principles composition properties various types biomass, analysis traditional popular optimization strategies, practical oxidative electrocatalysts. provides advances provide research directions design ideas catalyst synthesis/optimization contributes industrialization electrocatalysis electric storage.
