Abstract

Cerium-containing mesoporous materials have been synthesized by hydrothermal method and characterized by IR, DR-UV-vis and DRIFT spectroscopy, XRD and N₂adsorption methods. It was established that the d₁₀₀and unit-cell (a₀) parameter increase with the increase of cerium content up to 2% in SBA-15 and then tend to remain the same. According to DR-UV-vis spectroscopic data, an agglomeration of cerium atoms was observed in the form of fine CeO₂crystallites. Important factors affecting the catalytic activity of Ce-SBA-15, namely the effect of cerium content, the state of cerium ions, the state of silanol groups on the surface of Ce-SBA-15, and stability of the catalyst have been studied in the cyclohexanol and cyclohexene oxidation with hydrogen peroxide.
