Photoreduction of CO 2 into solar fuels is usually regarded as one of the promising solutions to overcome environmental pollution and the energy crisis. The main challenge in CO 2 photoreduction (CO 2 PR) is the low efficiency and poor selectivity. Layered double hydroxides (LDHs) are a class of 2D materials, consisting with M(OH) 6 octahedra in the host layers and intercalated anions. Owing to the tuneable composition, particle size, morphology, and virtue coordinatively unsaturated active sites, a series of efficient strategies (morphology control, heterostructure, defect control, etc.) in LDH‐based photocatalysts have been efficiently developed to enhance the photocatalytic selectivity and activity for CO 2 PR. This review summarizes recent progress on the LDH‐based photocatalysts for CO 2 PR.
