Abstract

A series of porous TiO2–SiO2 mixed metal oxides were synthesized via sol–gel route using n-alkyl amine as pore directing templates. The mixed oxides were characterized by nitrogen physisorption for surface area, pore volume and pore size distribution, as well as by FTIR, TGA, SEM, and TEM for the dispersion of titanium. These compounds are good catalysts for liquid phase epoxidation of cyclohexene using hydrogen peroxide as the oxidant. The effects of various factors on catalyst reactivity were also studied. The catalysts performance and selectivity are enhanced in protic solvents when compared to aprotic solvents.
