Recently, the missing link between homogeneous and heterogeneous catalysis has been found it was named single-atom (SAC). However, SAC field still faces important challenges, one of which is controlling bonding/coordination single atoms support in order to compensate for increase surface energy when particle size reduced due atomic dispersion. Excellent candidates meet this requirement are carbon nitride (CN)-based materials. Metal can be firmly trapped nitrogen-rich coordination sites CN materials, makes them a unique class hosts preparing catalysts (SACs). As most promising two-dimensional supports stabilize isolated metal atoms, materials have increasingly employed SACs. Herein, we will cover recent advances single-atoms supported by In review, characterization techniques challenges faced topic discussed, commonly synthetic methods delineated different Finally, catalytic performance SACs based on nitrides reviewed with special focus their photocatalytic applications. particular, prove as non-innocent support.

Recent Progress of Single‐Atom Photocatalysts Applied in Energy Conversion and Environmental Protection

Small, Journal Year: 2023, Volume and Issue: 19(22)

Published: Feb. 28, 2023

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.
