We have successfully prepared Ti-containing hierarchical macroporous silica with mesoporous frameworks (Ti-MMS) using organic surfactant and poly(methyl methacrylate) microspheres.  Ti-MMS exhibited higher catalytic activities for epoxidation of linear α-olefin compared with Ti-containing mesoporous silica without macropores, due to the advantageous of the combination of hierarchical macroporous and mesoporous structures.
