Three-dimensional Mesoporous TiKIT-6 with Ia3d Symmetry Synthesized at Low Acid Concentration and Its Catalytic Performances
Here we report for the first time oil the preparation of well-ordered titanium substituted KIT-6 at low acid concentration using polymeric surfactant. The characterization results show that the pore diameter and the unit cell constant of TiKIT-6 increase with increasing Ti incorporation. UV-vis results reveal that most of the Ti are in tetrahedral coordination. In addition, the materials showed higher activity in the epoxidation of styrene than TiSBA-15.
