| Abstract: | Ti containing KIT-1 materials with well ordered long-range and pore structures were prepared by grafting Ti onto the surface of KIT-1. Ti-grafted KIT-1 materials were used as the catalyst for the hydroxylation of benzene. Catalytic performance and stability of the catalyst were investigated. The results show that Ti-grafted KIT-1 with hydrophobic surface is much more reactive in the hydroxylation of benzene than that of phenol. The long-range and pore structures of KIT-1 are also stable enough in the hydroxylation. |
