One of the best solutions to these two issues is thought to be the photocatalytic reduction of CO 2 into value-added carbon-containing products. In this aspect, the main challenges mainly include the photocatalytic mechanism, reaction activity, and product selectivity, especially in ambiguous reaction pathways and product selectivity, an unclear charge transfer mechanism, and an overestimate of product yield. Therefore, in this perspective, we attempt to exhibit the discussion and in-depth analysis of the possible reaction pathways and product selectivity, the specific charge transfer mechanism, and the origin of carbon-containing products in phtocatalytic CO 2 reduction. Besides, the fundamentals for photocatalytic CO 2 reduction are also illustrated. Finally, the state-of-the-art challenges and perspectives in CO 2 photoreduction are highlighted and discussed in detail. This perspective is expected to evoke more research attention for the photocatalytic reduction of CO 2 into value-added products.
