Ethanol Reforming with CO 2 over MOF-derived CoMO X (m:Ce,zr,zn): Impact of Support on Activity/stability

Recently, bio-ethanol reforming with CO2 (EDR) has been considered as one of the environment-friendly processes to diminish the emission of greenhouse gas, along with increasing the production of value-added syngas. However, designing high-performance catalysts is still a great challenge. In this work, MOF-derived CoMOx (M:Ce,Zr,Zn) catalysts were applied in EDR reaction for the first time to explore the influence of support types on catalytic performance. Characterization of the investigated catalysts by XPS, XRD, H2-TPR, Raman, TEM and BET depicted the difference in cobalt dispersion, specific surface area as well as Co-support interaction. Indeed, H2-TPR and XPS results revealed stronger Co-Ce interaction and the smaller particle size of Co3O4 in Co-CeO2 catalyst which contributed to higher activity. Indeed, 100
