摘要：

Titanium silicalite (TS-l) samples with increasing amount of titanium incorporated into the silicalite framework (from 1 to 3.45 wt.% TiO(2)) have been synthesized and characterized by W-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-I, expressed as turnover number, increases with the Ti content. The trend is common for all the reactions investigated.
