Influence of Ce2O3 and CeO2 promoters on Pd/MgO catalysts in the dry-reforming of methane

In this study, the conversion of methane and CO 2 to synthesis gas using dry reforming over Pd/MgO catalysts using different concentrations of Ce 3+ and Ce 4+ was investigated. Moreover, the factors that contribute to the deposition of carbon during the co-precipitation method were examined. The catalysts used in this study were prepared using K 2 CO 3 as the precipitant. The characterization of the catalysts was performed using state-of-the-art techniques such as XRD, XPS, FT-IR, TPR-H 2 , BET, TEM, FE-SEM, and TGA. It was found that with the addition of Ce promoter, the Pd/Mg 0.85 Ce 015 O catalyst exhibited a high level of activity (CH 4 : 54%, and CO 2 : 74%) with excellent stability. The results of this analysis also revealed the outstanding anti-coking activity of the reduced catalyst with low Pd metal. In addition, we studied the catalytic performance and stability of the produced catalysts.
