Recent progress of modification of mesoporous silica SBA-15

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.
