Abstract Energy shortages and global warming are two main problems the world is currently facing. Photocatalytic CO 2 reduction is one of the most promising solutions to the above issues. Among the various photocatalysts, faceted TiO 2 crystals have attracted wide attention due to their excellent photocatalytic performance for CO 2 reduction. This review encompasses the recent advances in the application of facet-engineered TiO 2 -based catalysts for CO 2 photocatalytic reduction. The review begins with the fundamentals of CO 2 photocatalytic reduction over TiO 2 . In the following section, we discuss the surface atom structure and electronic structure of faceted TiO 2 crystals and the related the CO 2 /water adsorption and charge transfer/separation properties. Then, we outline the modification strategies for faceted TiO 2 and their influence on the CO 2 photocatalytic reduction performance. Finally, a summary and the future perspectives of facet-engineered TiO 2 photocatalysts for CO 2 photoreduction are presented.
