摘　　要：层状双金属氢氧化物是一类重要的阴离子层状材料,通过调变层间阴离子的种类和数量,可以得到性能丰富的复合材料.多金属氧酸盐(简称多酸)是一类结构明确、种类多样、性能丰富的阴离子材料.将多酸插入阴离子层状材料中,可以实现电荷平衡以及尺寸匹配,并且主体和客体之间的多重相互作用有助于多酸的分散和稳定.这类多酸插层水滑石复合材料在环境、能源、催化等领域具有重要的应用.本文综述了近年来多酸插层水滑石材料的制备方法及其在不同应用领域的最新进展.Layered double hydroxides （LDHs） or hydrotalcite-like compounds are an important large family of two-dimensional （2D） anionic clay materials which possesses flexible tunability, uniform distribution of metal cations in the layers, and the facile exchangeability of intercalated anions. Polyoxometalates （POMs） are a class of V, Mo, and W-containing discrete anionic metal oxides that can be viewed as transferable building blocks. Owing to the modular accessible gallery and unique inter-lamellar chemical environment, the POMs intercalated LDHs have shown wide application in environment, energy, catalysis, etc. This review mainly focuses on the summary of synthetic strategy and recent development of the POM/LDHs composite materials.
