Abstract

Mesoporous metal oxides and sulfides were prepared by a simple solvothermal method using inorganic salts as metal sources and diethylene glycol (DEG) as solvent; they are formed by the aggregation of metal compound nanoparticles. The generality of this route to the mesoporous materials was proved by the fabrication of a series of mesoporous materials (TiO(2), ZrO(2), ZnO, In(2)O(3), ZnS, and In(2)S(3)). Due to the different morphologies of nanoparticle subunits, the as-prepared mesoporous materials had different types of mesopores, which could be revealed by the N(2) adsorption-desorption isotherms and transmission electron microscopy (TEM) images.

摘要

介孔金属氧化物和硫化物是通过简单的溶剂热方法制备的，使用无机盐作为金属源，二乙二醇（DEG）作为溶剂；它们是由金属化合物纳米粒子的聚集形成的。通过制备一系列介孔材料（TiO(2)、ZrO(2)、ZnO、In(2)O(3)、ZnS 和 In(2)S(3)）证明了这种介孔材料的通用性。由于纳米粒子亚基的不同形态，所制备的介孔材料具有不同类型的介孔，可以通过 N(2)吸附-解吸等温线和透射电子显微镜（TEM）图像揭示出来。
