Catalytic performance of surface-silylated and phenyl-bridged Ti-containing mesoporous silica for epoxidation of propylene

A surface-silylated and phenyl-bridged Ti-containing mesoporous silica material was constructed by incorporating titanium component and phenyl groups in situ in the crystallization process before surface silanization. The material was characterized by various means to demonstrate its properties of structure and environment of active site. The catalytic performance of prepared material was evaluated in propylene epoxidation and obtained the optimized reaction conditions.195
