The concept of photocatalytic reduction of carbon dioxide (CO2) into solar fuels has received considerable attention. This approach could resolve the environmental issue and the energy crisis synergistically. In this study, several possible products and reaction pathways of CO2 reduction that might happen under different conditions are summarized. Various photocatalysts and their mechanism for the reduction of CO2 into C1 and C2+ products are highlighted and overviewed. In addition, we address the yet unresolved questions concerning the insight of the mechanism and tailoring photocatalysts, which can bring more insights for enhancing photocatalytic efficiency. Finally, we provide the remaining challenges and prospects for the development of photocatalytic CO2 reduction.
