摘要
A simple and economic method was developed to synthesize Ti-containing MCM41 from titanium sulphate as Ti source, sodium metasilicate as Si source and cetyltrimethylammonium bromide (CTABr) as template. The resultant materials were characterized by using XRD, FT-IR, N2 adsorption isotherms, HRTEM, ICP, and LRS techniques. It was revealed that the atoms of titanium were incorporated into the framework of MCM41 for the samples with Ti / Si mol ratios below 1 / 20. Small amount of titanium oxides that highly dispersed onto the wall of MCM41 were detected while the Ti / Si mol ratios up to 1 / 10. The prepared materials exhibited high catalytic activity in the oxidation of aromatic compounds.
