Titannium Silicalite

Titannium Silicalite-1 (TS-1) is isomorphic to ZSM-5 and both belong to the MFI topological structure. Therefore, they also possess a unique ten-ring cross-pore channel system. The difference is that in ZSM-5 molecular sieve, some of the framework silicon atoms are substituted by aluminum atoms in the same crystal lattice, while in TS-1, some of the framework silicon atoms are replaced by titanium atoms in the same crystal lattice. The framework titanium atoms in TS-1 can activate hydrogen peroxide, thereby enabling the epoxidation of alkenes and the ammoxidation of cyclohexanone. Additionally, the catalytic system composed of TS-1 and dilute hydrogen peroxide can also lead to the selective oxidation of alcohols and alkanes, as well as the hydroxylation reaction of phenol.
