Abstract
MFI-type titanosilicate zeolite TS-1 is synthesized via a newly developed mechanochemical route, and the effects of mechanochemical reaction conditions on the physical and chemical properties are investigated. In the mechanochemical route, titania and silica powders are ground by using a planetary ball mill to yield a silica-titania composite powder, which is converted into TS-1 through hydrothermal treatment. TS-1 samples are characterized by powder X-ray diffractometry and UV-visible spectroscopy, and their catalytic activities in the alkene oxidation reaction are evaluated. Several parameters of the mechanochemical reaction such as the disk rotation speed, the grinding time, and the molar ratio of silica and titania are changed to evaluate their effects on the properties of resulting materials. It is demonstrated that these parameters have significant effects on the physical and chemical properties of the final product.
