英文摘要the investigation of the active centers in titanium zeolite was conducted by a probe reaction, the oxidation of trimethylphosphine. the different sites of ts-1 zeolite can be clearly distinguished through p-31 solid-state mas nmr spectra of adsorbed trimethylphosphine. the results showed that only the trimethylphosphine bound to the coordinate-unsaturated framework ti sites and the distorted tetrahedral ti sites ofts-1 zeolite could be easily oxidized by urea hydrogen peroxide. diffuse reflectance uv-vis and si-29 mas nmr spectra further confirmed that the titanium peroxide species (tiooh), which is formed through the solid-solid interaction between urea-h2o2 and ts-1 zeolite, could be catalytic active centers during the oxidation of trimethylphosphine.
