Three-dimensional Mesoporous TiKIT-6 with Ia3d Symmetry Synthesized at Low Acid Concentration and Its Catalytic Performances

Here we report for the first time on 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 resul...

Zusammenfassung:Here we report for the first time on 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.
