Catalysis and Hydrodesulfurization Studies

Titanium silicalite (TS-1) samples with increasing amount of titanium incorporated into the silicalite framework (from 1 to 3.45 wt.% TiO2) have been synthesized and characterized by UV-DRS spectroscopy. The samples have been tested on propylene epoxidation, cyclohexanone ammoximation and ammonia oxidation reactions. It has been found that the yield obtained with TS-1, expressed as turnover number, increases with the Ti content. The trend is common for all the reactions investigated.
