Recent Progress on Photocatalytic CO₂ Reduction with Earth-abundant Single-atom Reactive Sites

Photocatalytic CO₂ reduction reaction represents a promising means of solar-fuel production through conversion of CO₂ feedstock. Suitable reactive sites are crucially important for ensuring high efficiency and good selectivity of target products. The construction of single-atomic reactive sites with earth-abundant materials on the surface of semiconductor can provide an efficient and cost-effective route of photocatalytic reaction, demonstrating great potential for photocatalytic CO₂ reduction reaction. Herein, we give a short review on the mechanism of photocatalytic CO₂ reduction reaction, single-atom reactive sites and the constructing strategies, recent progress and future perspectives of single-atom reactive sites with earth-abundant materials for photocatalytic CO₂ reduction reaction.
