Advances in mesoporous silica materials with complex morphology and their applications

Abstract

According to the regulations of the International Union of Pure and Applied Chemistry, the mesoporous nanoparticle is a material with a pore diameter of 2-50nm. Due to mesoporous the high specific surface area, regularly ordered pore structure and continuously adjustable pore size of mesoporous materials, they have been continuously concerned by researchers since the synthesis by Mobil R & D in the year of 1992, and have been applied to catalysis, adsorption, biomedicine and many other fields. By the way, the materials still enjoy a promising development prospect.

This thesis takes time as the mainline and mainly summarizes the development history of mesoporous silica, ranging from its main morphologies, structures, synthesis approaches, and application and development of silica materials with complex morphology. The first chapter mainly summarizes the development of mesoporous materials and the synthesis methods of mesoporous silica materials with simple morphology. The second chapter mainly introduces the development history from the appearance of mesoporous silica materials with complex shapes, as well as the main complex shapes, synthesis methods, etc. In addition, some vivid illustrations are also added to this article to help readers quickly understand mesoporous silica materials with complex morphology. The third chapter is based on the former chapter, summarizing the application of the mesoporous silica materials with complex morphology mentioned in drug delivery, catalysis and enhancement of interaction between biomolecules.
