摘要：
Ru-Ce supported catalyst properties were studied with the aim of improving catalytic performance in phenol abatement from aqueous solutions by investigating the effect of different thermal pretreatments under a flow of helium. Characterization using TGA, XRD, TEM and XPS shows that ruthenium acetylacetonate was more highly dispersed than CeO(2). Ru-Ce/HSAG samples show increased Catalytic Wet Oxidation (CWO) of phenol compared to Ru/CeO(2), Ru/HSAG and Ce/HSAG. The Ru-Ce sites generated during the preparation and activation of the Ru-Ce/HSAG catalyst at 473 K, result in higher activity, conversion and mineralization values in the phenol CWO.
