Titanium silicalite 1 (TS-1) catalyst was prepared by three different hydrothermal synthesis methods. XRD, elemental analysis, SEM, IR, 29Si MAS NMR, UV-vis DRS, physical adsorption of nitrogen, and EXAFS analysis were then performed to evaluate its physical properties. For a test of catalytic activity, liquid phase 2-butanol oxidation and 1-hexene epoxidation using hydrogen peroxide as an oxidant were conducted. The crystal size of the TS-1 catalyst was shown to have a considerable effect on the 1-hexene epoxidation, and smaller crystals resulted in higher activity.
