英文摘要Titanium-containing MEL zeolites (Ti-ZSM-11) are prepared by gas-solid reactions between TiCl4 vapor and B-ZSM-11 precursors. XRD, FTIR, UV-Vis, B-11 and Si-29 MAS NMR techniques are used to characterize these materials. The results show that Ti atoms are incorporated into the silanol nests that were previously occupied by B atoms. The precursor deboronated by acid reflux possesses a large amount silanol nests and so can obtain a high concentration of titanium in the framework, compared to the directly calcinated precursors. Ti-ZSM-11 zeolites are used to catalyze the epoxidation of propylene with dilute hydrogen peroxide. The results show that the catalytic activities are related to the physicochemical properties of these materials. (C) 2000 Elsevier Science B.V. All rights reserved.
