介孔分子筛SBA-15的改性研究进展

Recent progress of modification of mesoporous silica SBA-15

从金属改性、酸改性和氧化物改性三方面综述了介孔分子筛SBA-15的改性研究进展,重点介绍了SBA-15表面功能化后引入金属改性的方法。评述了金属纳米粒子的制备对改性的SBA-15催化剂催化性能的影响。

Mesoporous silica SBA-15 has excellent physicochemical characteristics and structure properties, but it has no catalytic active sites because SBA-15 is composed of pure silica, and needs to be modified to introduce catalytic active sites. The recent progress of modification of mesoporous silica SBA-15 is reviewed in terms of three aspects, metal modified SBA-15 catalysts, acid modified SBA-15 catalysts and oxides modified SBA-15 catalysts. The effect of metal nanoparticles preparation on the catalytic properties is discussed.
