This minireview summarizes the typical metal-support interaction patterns for anchoring single-atom metals on metallic compound supports. It highlights the contribution of dispersed single metal atoms and metal-support interaction to photocatalytic reactions, and proposes future challenges and perspectives.
Metal atoms atomically dispersed on an inorganic metal-based support compose a unique category of single atom catalysts (SACs) and have important applications in catalytic photoreduction reactions, including H-2 evolution reaction, CO2 reduction reaction, and N-2 reduction reaction. In this minreview, we summarized the typical metal-support interaction (M-SI) patterns for successful anchoring of single-atom metals on metallic compound supports. Subsequently, the contribution of the dispersed single metal atoms and M-SI to photocatalytic reactions with improved activity, selectivity, and stability are highlighted, such as by accelerating charge transfer, regulating band structure of the support, acting as the reductive sites, and/or increasing catalytic selectivity. Finally, some challenges and perspectives of future development are proposed. We anticipate that this minireview will be a beneficial supplement for a comprehensive perception of metal-based material supported SACs and their application in heterogeneous photo-reductive catalysis.
