Fabrication of Crystalline Mesoporous Metal Oxides and Sulfides

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)
