Titanium-rich TS-1 zeolite for highly efficient oxidative desulfurization

The exploration of highly efficient catalysts based on nano-sized Ti-rich titanosilicate zeolites with controllable active titanium species is great importance in zeolite catalytic reactions. Herein, we reported an and facile synthesis TS-1 (MFI) by replacing tetrabutyl orthotitanate (TBOT) tetramer (TBOT-tetramer) as the source. introduced TBOT-tetramer slowed down crystallization process, accordingly balanced rate incorporating Ti crystal growth inhibited massive formation anatase species. Notably, prepared sample had a Si/Ti low 27.6 contrast to conventional one molar ratio 40. endowed enriched enlarged external surface area. It also impeded species, resulting superior behavior toward oxidative desulfurization dibenzothiophene compared counterpart TBOT.
