Abstract

A novel MCM-41-supported base catalyst, Ba-MCM-41, was synthesized with a modified impregnation method. Ba₂SiO₄ was synthesized on the MCM-41 pore wall as confirmed by characterization using X-ray diffraction, X-ray photoelectron spectroscopy, X-ray fluorescence, N₂ adsorption, ²⁹Si MAS NMR and transmission electron microscopy. It was also demonstrated that a highly ordered Ba-MCM-41 catalyst with high barium loading (4.1-25.2 wt.%) and dispersion was obtained using this method. The basicity of the catalyst, which was characterized according to the binding energy of O 1s, was increased with increasing amounts of barium in the catalyst.
