摘要:

基于硅酸脂水解/缩合的溶胶-凝胶法是目前制备SiO2胶体最为常用的化学方法. 在溶胶-凝胶反应过程中, 引入介孔导向剂(通常是表面活性剂)可以得到具有介孔结构的SiO2胶体. 通过对硅酸脂在多相体系界面水解/缩合过程的调控, 可以构筑具有不同纳微结构的介孔SiO2材料, 为拓展介孔SiO2材料的应用领域提供了新机遇, 同时也丰富了对溶胶-凝胶法的理解和认识. 本文综述了利用溶胶-凝胶法构筑介孔SiO2纳微结构的最新研究进展, 并介绍了其在生物医药、 催化、 吸附分离等领域的应用前景, 最后对这一领域所面临的问题和未来发展方向进行了总结和展望.

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
