Using sunlight to drive chemical reactions via photocatalysis is paramount for a sustainable future. Among several photocatalysts, employing layered double hydrides (LDH) for photocatalytic application is most straightforward and desirable owing to their distinctive two-dimensional (2D) lamellar structure and optical attributes. This article reviews the advancements in bimetallic/trimetallic LDHs and various strategies to achieve high efficiency toward an outstanding performing photocatalyst. Firstly, the tuning of LDH components that control the electronic and structural properties is explained. The tuning obtained through the adoption, combination, and incorporation of different cations and anions is also explained. The progress of modification methods, such as the adoption of different morphologies, delamination, and defect engineering towards enhanced photocatalytic activities, is discussed in the mainstream.
