摘要: LDHs(layered double hydroxides)是一类具有双金属氢氧化物层结构的新型无机材料,其酸碱性、热稳定性、层间阴离子可交换性以及结构记忆效应等特性在诸多领域中得到了广泛应用,成为当前研究的热点。针对国内外研究现状,本文综述了LDHs材料的基本性质、层间不同种阴离子及插层阴离子的化学作用。在此基础上,概括了LDHs材料的制备、表征方法和相关领域的应用,介绍了其在不同溶剂中进行剥离的研究进展,指出能否将其工业化扩大生产是制约其应用的重要因素,同时也分析了当前需要解决的相关问题,为今后LDHs材料的研究提供借鉴。

Abstract: LDHs (layered double hydroxides) are one class of new inorganic materials with special layer structures. Owing to the acid and basic properties,thermal stability,interlayer anionic interchangeability and structure and memory effect,layered double hydroxides (LDHs) have been used in many fields,and have become research hot spot at the present. Aiming at the present status,different interlayer ions,chemical effects and basic properties of LDHs are reviewed. Applications,preparation and characterizing methods of LDHs are summarized,and delamination in different solvents is introduced. The most important factor limiting its application is whether LDHs could be commercially produced. Some problems which need to be resolved in the future are analyzed to provide the reference for the study of LDHs.

Key words: layered double hydroxides (LDHs);HTLc;new inorganic materials;structure, properties
