Oxygen evolution reaction (OER), as an important process in water splitting has attracted more and more attention in clean energy production and efficient energy storage. Layered double hydroxides (LDHs) are typical two-dimensional materials with unique layered structures, high specific surface area, exchangeability of metal ions, diversity of intercalated anions and unique electron distribution, which can serve as catalysts for OER. However, their poor conductivity limits their application in catalysis. In this review, three classes of LDHs materials, including pure LDHs, LDHs derivatives and LDHs composites are systematically reviewed and their development and applications in OER are comprehensively presented. Moreover, further research methods and directions on LDHs as OER catalysts were also prospected. In particular, this review highlights the potential synthesis-structure-property correlations of these layered materials. These will provide guidance for designing efficient OER electrocatalysts and evaluating their performance.

用于高效析氧反应的过渡金属基层状双氢氧化物及其衍生物

析氧反应（OER）作为水分解的重要过程，在清洁能源生产和高效能源储存方面受到越来越多的关注。层状双氢氧化物（LDHs）是典型的二维材料，具有独特的层状结构、高比表面积、金属离子交换性、插层阴离子多样性和独特的电子分布，可作为OER催化剂。然而，它们较差的导电性限制了它们在催化领域的应用。本文系统综述了三类LDHs材料，包括纯LDHs、LDHs衍生物和LDHs复合材料，并全面介绍了它们的发展和在OER中的应用。此外，还对LDHs作为OER催化剂的进一步研究方法和方向进行了展望。特别是，这篇综述强调了这些层状材料潜在的合成-结构-性能相关性。这些将为设计高效的 OER 电催化剂和评估其性能提供指导。
