Recent Advances on Single-Atom Catalysts for Photocatalytic CO Reduction.

The present energy crisis and environmental challenges may be efficiently resolved by converting carbon dioxide (CO ) into various useful carbon products. The development of more effective catalysts has been the main focus of current research on photocatalytic CO reduction. Due to their high atomic efficiency and superior catalytic activity, single-atom catalysts (SACs) have attracted considerable interest in catalytic CO conversion. This review discusses the current research developments, obstacles, and potential of SACs for photocatalytic CO reduction. And further, discusses the principle of photocatalytic carbon dioxide reduction. This work has compared and analyzed the effects of support materials and active site types in SACs on photocatalytic CO reduction performance. This work believes that by sharing these developments, some inspiration for the rational design and development of stable and effective photocatalytic CO reduction catalysts based on SACs can be provided.
