Photocatalysts for Photocatalytic CO2 Reduction:A Review

Energy crisis and environmental pollution have become vitally severe challenges for the current society.During the circumstances of pursuing carbon peak and carbon neutrality,photocatalytic COreduction will be an essential,necessary and even inevitable development requirement and trend.However,there are some bottlenecks that need to be addressed immediately,such as low quantum efficiency and narrow light absorption range for single photocatalysts.Therefore,efficient and stable visible light driving materials are the core challenge in the field of photocatalytic COconversion.This paper reviewed the photocatalysts used for COreduction classified as metal photocatalysts,non-metal photocatalysts,and MOFs photocatalysts,and the COreduction capacity and mechanism of different photocatalysts were described.In the end,the problems to be solved and the future development of photocatalytic COreduction were summarized.
