Wang Guiru Wang Bo Abstract: Using silica sol as the silicon source, inorganic titanium as the titanium source, hexamethylene diamine and tetraethylammonium hydroxide as the template, the Ti-SiZSM-5 (TS-1) molecular sieve was prepared by hydrothermal synthesis. The synthesized molecular sieves were characterized by XRD, FT-IR, UV-Vis, and NH3-TPD. The catalytic performance of the synthesized molecular sieve for the hydroxylation of phenol and selective oxidation of styrene was also investigated.
