Abstract:

The hydrolysis/condensation of orthosilicate is the most commonly used chemical method for the preparation of silica materials. During the sol-gel reaction, the addition of mesoporous-directing agent(i.e., usually a surfactant) results in silica materials with a mesoporous structure. By adjusting the hydrolysis/condensation process in a multiphase interface, different mesoporous nanomicrostructures are constructed. This provides new opportunities for expanding their application fields and enriches the understanding of the sol-gel method. This paper systematically introduces the latest research progress in the sol-gel construction of mesoporous silica nanomicrostructures, including application prospects in biomedicine, catalysis, adsorption separation, and summarizes the problems faced in the fields and the future development direction.

Key words: Sol-gel method, Mesoporous silica, Nanomicrostructure
