Abstract：Metallic photocatalysts attracted much attention due to their special band structure, which could absorb near-infrared light to drive photocatalytic reaction. Firstly, the basic principle of metallic photocatalysts and the challenges in photocatalytic CO2 reduction field were reviewed. Secondly, in view of the bottleneck faced by the metallic photocatalysts, the effects of several current modification strategies on improving the CO2 photoreduction activity of metallic photocatalysts were summarized. And the relationship between the catalyst structure and the photocatalytic performance was examined carefully. Finally, the future development trend and the research direction of metallic photocatalysts were explored.
