英文摘要: Titanium-containing MFI zeolites (Ti-ZSM-5) have been prepared by gas-solid reaction between highly siliceous ZSM-5 precursors synthesized with different organic molecules, and TiCL4 vapor at elevated temperature. XRD, FT-IR, UV-Vis, Si-29 and Al-27 solid NMR techniques are used to characterize precursors and Ti-ZSM-5 zeolites. Highly siliceous ZSM-5 synthesized with different templates possesses different amount of internal silanol groups clustered as silanol nests in framework. When the precursor is contacted with TiCl4 vapor at elevated temperature, titanium atoms are incorporated into the tetrahedral sites by the reaction between TiCl4 and silanol nests, not by the isomorphous substitution of titanium for framework aluminium or/and silicon. Highly siliceous ZSM-5 precursor synthesized with NEA, TEABr or HDA template possesses relatively large amount of internal silanol groups, and then obtains high concentrations of framework titanium after contacted with TiCl4 vapor, compared to those synthesized with TPAOH or TPABr template. In addition, Ti-ZSM-5 with precursors obtained by using NEA, TEABr or HDA template can occupy higher catalytic activity in the epoxidation of propylene with diluted hydrogen peroxide.
