Abstract: Mesoporous TiO2-CeO2(m-TiO2-CeO2) was synthesized using n-cetylpyridinium chloride(C16PyCl) as a structure-directing agent under room temperature and neutral condition. The as-synthesized mesoporous samples were characterized by FT-IR, XRD, and N2 adsorption methods. The incorporation of Ce4 + ions into the channel wall dramatically improves the mesoporous structure. After ruthenium loaded by the impregnating method, the Ru particles strongly interact with the mesoporous mixed supports. Although a fairly large part of the particles are considered to be confined in the blind pores, the catalytic activity of ruthenium supported on m-TiO2-CeO2 for methanol decomposition to carbon monoxide and hydrogen is significantly higher than that of ruthenium supported on m-TiO2. A synergistic effect between Ru and CeO2 was observed for promoting the catalytic properties of Ru.
