Innovative Strategies for Oxygen Evolution Reaction Using Layered Double Hydroxide‐Based Electrocatalysts

Abstract Layered double hydroxides (LDH) catalysts are widely used in oxygen evolution reaction (OER), but are limited by their low conductivity, few active sites, and poor stability. For this reason, various modification strategies have emerged. In this review, the mechanistic explanation direction of the OER performance enhancement of modified LDH was elaborated from a mechanistic point of view, which mainly includes the heterostructure‐dominated synergistic effect, doping‐induced lattice distortion and multi‐element electronic interaction. The substantial improvements in OER performance achieved through LDH modification can be considered by focusing on the above three mechanisms. Subsequently, a detailed exploration of the existing shortcomings in the explanation of LDH modification mechanisms for OER was conducted. By addressing these gaps, we aim to offer more effective guidance for the rational design and broad application of LDH‐based catalysts in OER processes in the future.
