英文摘要TiO2 modified Al2O3 binary oxide was prepared by a wet-impregnation method and used as the support for ruthenium catalyst. The catalytic performance of Ru/TiO2-Al2O3 catalyst in CO2 methanation reaction was investigated. Compared with Ru/Al2O3 catalyst, the Ru/TiO2-Al2O3 catalytic system exhibited a much higher activity in CO2 methanation reaction. The reaction rate over Ru/TiO2-Al2O3 was 0.59 mol CO2.(g Ru)(-1).h(-1), 3.1 times higher than that on Ru/Al2O3 [0.19 mol CO2.(g Ru)(-1).h(-1)]. The effect of TiO2 content and TiO2-Al2O3 calcination temperature on catalytic performance was addressed. The corresponding structures of each catalyst were characterized by means of H-2-TPR, XRD, and TEM. Results indicated that the averaged particle size of the Ru on TiO2-Al2O3 support is 2.8 nm, smaller than that on Al2O3 support of 4.3 nm. Therefore, we conclude that the improved activity over Ru/TiO2-Al2O3 catalyst is originated from the smaller particle size of ruthenium resulting from a strong interaction between Ru and the rutile-TiO2 support, which hindered the aggregation of Ru nanoparticles.
