Photocatalytic CO2 reduction can be implemented to use , a greenhouse gas, as resource in an energy-saving and environmentally friendly way, which suitable catalytic materials are required achieve high-efficiency catalysis. Insufficient accessible active sites on the catalyst surface inhibited electron transfer severely limit photocatalytic performance. Therefore, porous aerogels constructed from composites comprising different ratios of Ni-Co bimetallic hydroxide (Nix Coy ) grown reduced graphene oxide (GR) into hierarchical nanosheet-array structure using facile situ growth method. Detailed characterization shows that this exposes numerous for enhanced adsorption-induced reduction. Moreover, under synergistic effect hydroxide, adsorption capacity well charge-carrier separation excellent. As result, Ni7 Co3 -GR exhibits highly improved performance when compared with recently reported values, high CO release rate 941.5 µmol h-1 g-1 selectivity 96.3% during . This work demonstrates new strategy designing nanocomposites abundant structures.

Abstract Photocatalysis driven by solar energy is a feasible strategy to alleviate crises and environmental problems. In recent years, significant progress has been made in developing advanced photocatalysts for efficient solar‐to‐chemical conversion. Single‐atom catalysts have the advantages of highly dispersed active sites, maximum atomic utilization, unique coordination environment, electronic structure, which become research hotspot heterogeneous photocatalysis. This paper introduces potential supports, preparation, characterization methods single‐atom detail. Subsequently, fascinating effects on three critical steps photocatalysis (the absorption incident light produce electron‐hole pairs, carrier separation migration, interface reactions) are analyzed. At same time, applications conversion protection (CO 2 reduction, water splitting, N fixation, organic macromolecule reforming, air pollutant removal, degradation) systematically summarized. Finally, opportunities challenges discussed. It hoped that this work can provide insights into design, synthesis, application promote development high‐performance photocatalytic systems.
