Descripción
Theeffectof thesupport inthe incorporationof cobaltoxide nanoparticlesonmesoporousmaterials (SBA-15) andmesopo rouscellular foam(MCF)was investigated. Thematerialswere characterized using various techniques. The XRDdiffraction patterns showed that the porous structures remained after cobalt incorporation,whilehigh-angleXRDof theMCFshowed CoOpeaks, in contrast toCo-SBA-15whichexhibitedCo3O4. This was confirmed by XPS technique. The SEM-EDS and HRTEM-STEMmicroscopy indicate a distribution of cobalt oxidesuniforminthesamplessynthesizedandtheaveragesize of the particles is 1.88nm. H2-TPR analysis highlighted the interactionbetweenthesupport surfacesandthemetaloxide(SMSI). It was observed that in the SBA-15 structure, small clustersof cobaltoxide formedwithastrong interactionwith silica, leading to high reduction temperatures. The catalysts activity was characterized in oxidation reactions of Methyl Phenyl Sulfide anda correlationwas observedbetween the characterizationresultsandtheenhancedselectivityandyield towardssulfoneexhibitedbyCo-MCF.
