In this study, silica supported ceria, ceria–cobalt mixed oxide, silica supported ceria–cobalt mixed oxide, pure ceria, and cobalt oxide (CeO₂/SiO₂, CeO₂–Co₃O₄ and CeO₂–Co₃O₄/SiO₂, CeO₂, and Co₃O₄) catalysts were prepared and evaluated for selective oxidation of cyclohexene to allylic products (i.e., 2-cyclohexen-1-ol and 2-cyclohexen-1-one). The above catalysts were prepared through co-precipitation and deposition co-precipitation methods. Various physical characterization techniques namely XRD analysis, BET studies, Raman studies, FE-SEM analysis, XPS analysis, and NH₃-TPD analysis were used to investigate the structure, morphology, surface area and the textural properties of the catalysts. The results have confirmed that the Co doped into the ceria and dispersed on silica leads to enhanced surface area, oxygen vacancies and the redox behavior of the catalyst. Among all these catalysts, the silica supported cobalt doped ceria catalyst CeO₂–Co₃O₄/SiO₂ showed superior catalytic activity towards cyclohexene oxidation reactions. Conversion of cyclohexene and selectivity for allylic products depend on various reaction parameters namely the reaction temperature, reaction time, amount of the catalyst, cyclohexene/oxidant ratios, and nature of the solvent.
