Ti负载对硅基MCM-41结构的影响
Effects of Titanium Loading on the Structure of MCM-41
摘要
Abstract
Titanium loaded MCM-41 mesoporous material was prepared by post-impregnation method. The effects of loading with Ti on the structure and catalytic performance of silica mesoporous material have been researched. XRD, FT-IR, Si MAS NMR, nitrogen adsorption-desorption isotherms and oxidation of styrene have been employed to characterize the specimens. It has been found that mesoporous still remains ordered mesostructure after loading with Ti. Ti atoms have been inserted into the framework of MCM-41. With the increase of Ti loading, part of Ti existed as TiO2. Compared with Si-MCM-41, the specific surface area was decresed and pore size distribution was narrow after loading with Ti. The oxidation of styrene showed that Ti/MCM-41 exhibited catalytic activity.关键词
