Single-atom catalysts on metal-based supports for solar photoreduction catalysis
Abstract
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 H2 evolution reaction, CO2 reduction reaction, and N2 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.
