This review surveys recent advances in the applications of layered double hydroxides (LDHs) in heterogeneous catalysis. By virtue of the flexible tunability and uniform distribution of metal cations in the brucite-like layers and the facile exchangeability of intercalated anions, LDHs-both as directly prepared or after thermal treatment and/or reduction-have found many applications as stable and recyclable heterogeneous catalysts or catalyst supports for a variety of reactions with high industrial and academic importance. A major challenge in this rapidly growing field is to simultaneously improve the activity, selectivity and stability of these LDH-based materials by developing ways of tailoring the electronic structure of the catalysts and supports. Therefore, this Review article is mainly focused on the most recent developments in smart design strategies for LDH materials and the potential catalytic applications of the resulting materials.
本文综述了层状双氢氧化物（LDHs）在多相催化中的应用的最新进展。由于水滑石层中金属阳离子的灵活可调性和均匀分布以及插层阴离子的易交换性，LDHs-无论是直接制备还是经过热处理和/或还原-已在各种具有重要工业和学术意义的反应中作为稳定且可回收的多相催化剂或催化剂载体得到了广泛的应用。在这个快速发展的领域中，一个主要的挑战是通过开发调整催化剂和载体的电子结构的方法，同时提高这些基于 LDH 的材料的活性、选择性和稳定性。因此，本文主要集中在 LDH 材料的智能设计策略的最新进展以及由此产生的材料的潜在催化应用。
