摘　　要：LDHs(layered double hydroxides)是一类具有相同结构、不同物理化学性质的阴离子层状无机功能材料,作为催化剂、催化剂载体和催化剂前驱体在催化领域得到了广泛的关注.本文综述了LDHs制备技术的最新发展,并从粒径控制、结晶度控制、形貌控制、含贵金属LDHs以及原位固载化等方面详细讨论了LDHs的可控制备技术.Layered double hydroxides （LDHs） refers to a large class of isostructurally layered anionic materials with different physicochemical properties, which have attracted increasing interests in recent years due to their potential application as catalysts, precursors of mixed oxide catalysts, and supports of catalysts. This paper is designed to review the state of the art in the preparation of LDHs. Particle size control and crystallinity control of LDHs, preparation of noble metal containing LDHs, macro-morphologically controlled preparation and in situ immobilization of LDHs are discussed in detail.
