Photocatalysis is a green technology used to drive chemical reactions under mild conditions, providing solutions to global energy and environmental issues. Layered double hydroxides (LDHs) have gained attention in photocatalysis due to their easy synthesis, low cost, and tunability. Recent research focuses on improving the performance of LDH-based photocatalysts through design strategies for high-performance solar fuel generation.
Photocatalysis is an ideal and promising green technology to drive numerous chemical reactions for valued chemicals production under very mild conditions, thereby providing solutions to global energy and environment issues related to burning fossil fuels. Over the past decade, layered double hydroxides (LDHs), as the members in two-dimensional materials family, have attracted much attention due to their many advantages in photocatalysis, such as facile synthesis, low cost and powerful tunability of composition. In this review, we provide a synthetic overview of recent research advances of LDH-based photocatalysts, with the main discussion of the design strategies to improve their photocatalytic performance, including component control, defect engineering, hybridization, and topological transformation. Structure-performance correlations and tailor-made material synthesis strategies are elaborated to discuss how to realize high-performance LDH-based photocatalysts for three important reactions (i.e., water splitting, CO2 conversion, and N-2 reduction) to generate desirable solar fuels. Further, the remaining challenges and future perspectives of LDH-based photocatalysts are summed up, aiming to inspire brand new solutions for pushing forward the development of LDH-based photocatalysis.
