Abstract
1 min read
This chapter describes the synthesis, spectroscopic characterization, and catalytic activity of titanium (Ti)-MCM-48 with different titanium loading. A series of Ti-MCM-48 materials with different Ti contents has been synthesized and characterized in the as-prepared and calcined states.The catalytic activity for the epoxidation of cyclohexene with tertbutylhydroperoxide on the different Ti-MCM-48 samples is tested. It has been possible to establish the dispersion of Ti (IV) sites on the silica surface by means of diffuse reflectance ultraviolet-visible (DR-UV-Vis) spectroscopy. These characterization results have been correlated with the final catalytic activity found for these mesoporous catalysts.
