Layered double hydroxides (LDHs) with their highly flexible and tunable chemical composition and physical properties have attracted tremendous attention in recent years. LDHs have found widespread application as catalysts, anion exchange materials, fire retardants, and nano-fillers in polymer nanocomposites. The ability to exfoliate LDHs into ultrathin nanosheets enables a range of new opportunities for multifunctional materials. In this review we summarize the current available LDH exfoliation methods. In particular, we highlight recent developments for the direct synthesis of single-layer LDH nanosheets, as well as the emerging applications of LDH nanosheets in catalyzing oxygen evolution reactions and preparing light emitting devices, supercapacitors, and flame retardant nanocomposites.
层状双氢氧化物（LDHs）具有高度灵活和可调的化学组成和物理性质，近年来引起了极大的关注。LDHs 已被广泛用作催化剂、阴离子交换材料、阻燃剂和聚合物纳米复合材料中的纳米填料。将 LDHs 剥离成超薄纳米片的能力为多功能材料提供了一系列新的机会。在这篇综述中，我们总结了目前可用的 LDH 剥离方法。特别是，我们强调了最近在直接合成单层 LDH 纳米片方面的进展，以及 LDH 纳米片在催化氧气析出反应以及制备发光器件、超级电容器和阻燃纳米复合材料方面的新兴应用。
