The uniqueness of TS-1 (Titanium Silicalite-1) catalyst lies in its structure, which incorporates titanium atoms within a silicate framework. This particular arrangement makes TS-1 highly selective and active, especially for the epoxidation of propylene to produce propylene oxide (PO) when using hydrogen peroxide (H2O2) as the oxidant. In this reaction, the titanium centers activate the H2O2, generating active oxygen species that selectively react with propylene to form PO.
