层状双氢氧化物析氧催化剂的制备及改性策略

Layered Double Hydroxides (LDHs) have garnered significant attention in the field of oxygen evolution reaction (OER) catalysis due to their unique layered structure, tunable chemical composition, and excellent electrochemical properties. The layered structure of LDHs consists of positively charged metal hydroxide layers and interlayer anions, which endows them with a high specific surface area and abundant active sites, making them exhibit superior performance in electrocatalytic reactions. Moreover, the chemical composition of LDHs can be precisely regulated by adjusting the types and ratios of metal elements in the layers and interlayer anions, thereby optimizing their catalytic activity, selectivity, and stability. These characteristics make LDHs one of the most promising materials in the field of OER catalysis. This article comprehensively and systematically reviews the synthesis methods and modification strategies of LDH-based catalysts, aiming to provide theoretical references and practical guidance for related research.
