Abstract Layered double hydroxides (LDHs)‐based photocatalysts have generated widespread interest owing to their great potential for solving both energy and environmental issues through directly converting nonconsumable solar energy. Numerous methods been investigated analyzed in recent years promote the photocatalytic efficiency of LDHs. Z‐scheme heterojunction that mimics artificial photosynthesis is employed photocatalysis outstanding advantages, such as high quantum efficiency, separation redox sites, low recombination photocarriers. Herein, various LDHs‐based are briefly reviewed. associated with materials exhibit performance, these types hybrids applied H 2 O splitting, CO reduction, pollution degradation, which introduced summarized detail. In end, a brief conclusion focused on future challenges expectations LDH‐based system presented. We expect more advances photocatalyst can be achieved field coming days.

Developing effective photocatalysts for CO2 reduction to high value-added chemicals or fuels is a promising strategy alleviating serious environmental problems and energy crisis. Currently, the photocatalytic efficiency still too slow arouse industrial interest most semiconductor due their low uptake, limited visible light capture capacity, recombination of electron–hole. Herein, we successfully synthesized high-density ultrafine Au cluster (∼0.7 nm)-doped cobalt-layered double hydroxide nanocage (Au/Co-LDH) photocatalyst through an in situ redox explore structure–activity relationship system. A series experimental characterizations showed that adsorption, charge transfer rate are significantly enhanced highly dispersed doping. Density functional theory calculations indicate doping also promoted redistribution at active site, increased density states near Fermi level, stabilized *COOH intermediate, reduced barrier rate-determining step. As result, Au/Co-LDH delivers CO evolution 5610 μmol g–1 h–1 toward under (λ > 420 nm), which 4 times 22 more than undoped one nanoparticles, respectively. We believe this work will provide important implication development optimization reduction.
