Transition metal‐based layered double hydroxides (LDHs) have been proved to be one of the most efficient materials for oxygen evolution reaction (OER), however, this kind of material still suffered from low conductivity and sluggish kinetics for hydrogen evolution reaction (HER), which largely inhibited the overall water splitting efficiency. To address this dilemma, enormous approaches including doping regulation, intercalation tuning and defect engineering are therefore rationally designed and developed.
Recently, a research team led by Prof. Dingsheng Wang from Tsinghua University, summarized recent exciting progress of LDHs hybridization with other two-dimensional (2D) materials for water splitting reactions. In this review, the authors firstly focused on synthetic methodology of the hybrids and followed by a detailed discussion on the structural features and their morphologies. The charge transfer, synergistic effects for the heterostructure/heterointerface between LDHs and 2D materials including carbon based material, MoS2 and Mxene, that influenced the electrocatalytic performance are then discussed. The authors also proposed the current challenges for the further energy application including the huge gap between laboratorial work and commercial applications.
This review will inspire the development of a new branch of advanced electrocatalyst for material science and energy application. The results were published in Chinese Journal of Catalysis (https://doi.org/10.1016/S1872-2067(21)63987-6).
