中文摘要Low loading catalysts Ru/ -Al2O3 and Ru-Ce/ -Al2O3 were prepared by thermolysis of Ru3(CO)12 on - Al2O3. The catalysts were characterized by XPS, XRD and SEM. Two new Ru species (RuA and RuB) were detected during the Ru3(CO)12 decomposition process due to chemical interaction with the active OH groups on the surface of Al2O3 support, and the reduction of them can lead to more dispersed metallic phases. The sample was completely decomposed at 673K in H2, and RuO2 was formed with minor amounts of Ru0.Whenthe temperature was increased to 773K to heat the sample, the ratio of Ru0 to RuO2 increased. However, after the addition of CeO2, only RuO2 was detected on surface. The catalysts exhibited high activities in Catalytic Wet Air Oxidation (CWAO) of different organic compounds at high concentration such as isopropyl alcohol, phenol, acetic acids and N,N-dimethylformamide, which is attributed to the better dispersion of Ru particles and the addition of CeO2 further enhanced number of effectively active sites on the cluster-derived catalyst surface.
