【摘要】 三维层状双金属氢氧化物简称3D-LDHs,是在制备普通二维层状金属氢氧化物(2D-LDHs)的过程中,改变反应条件得到的三维结构产物。它的组成单元与二维产物相同为完整LDHs纳米片,基本保留了LDHs具有的碱性、阴离子可交换性和记忆效应等特点,同时又因三维结构获得了更大的比表面积、丰富的孔隙结构以及形成复合材料的能力,在吸附、催化和电化学等方面的应用性能得以增强。本文概述了3D-LDHs的组成结构、主要制备方法及产物形貌,并对未来的研究方向进行了展望。更多还原

【Abstract】 Three-dimensional layered double hydroxides for short 3 D-LDHs,are the three-dimensional products obtained by changing the reaction conditions during the preparation of two-dimensional layered double hydroxides( 2 D-LDHs). Its component unit is the same as two-dimensional products as a complete LDHs nanosheet,retains the basic characteristics of basic,anionic exchangeability and memory effect. At the same time,it shows the performance of absorption,catalytic ability and electrochemistry resulting from larger surface area,porous structure and he ability to form composites. In this paper,the composition and structure of 3 D-LDHs,the main preparation methods and the morphology of the products are summarized,and the future research directions are prospected.更多还原
