多级结构微/纳米SiO_2球的合成与应用研究

Researching on the synthesis and application of spherical silica micro/nanomaterials with hierarchical structures

多级结构微/纳米材料SiO2球有4种主要的结构类型,中空介孔球、核-中空多孔壳球体、囊泡和多级孔球。介绍了材料合成的硬模板法、软模板法和其他几种特殊方法,简述了材料在药物、催化剂载体及模板等方面的应用。并对材料发展前景进行了展望。

The spherical silica micro/nanomaterials with hierarchical structures were classified into four main structural categories that including（1）hollow mesoporous spheres,（2）core-in-（hollow porous shell）spheres,（3）hollow spheres with multiple porous shells and（4）hierarchical porous spheres.The hard-templating method,soft-templating method or other methods and the application of drug and catalyst carriers,templates were reviewed.And the prospects of its development were also predicted.
