Ethylene glycol, a bio-based feedstock, offers a sustainable route for high purity H 2 production. In the current investigation, MgO based mixed metal oxides con- taining CeO 2 , La 2 O 3 and ZrO 2 were synthesized and used to support 20 wt% NieCu (1:1). The impacts of altering support characteristics on catalytic behavior have been studied and compared in H 2 synthesis via ethylene glycol steam reforming (SR), employing various characterization techniques such as XRD, SEM, EDX, TEM, H 2 -TPR, H 2 -TPD, TG-DSC and BET. Further, high resolution XPS studies were performed to explore the valence states and effectiveness of surface engineering of the catalysts. Assessment of the efficacy of catalysts was done via several parameters such as reactant conversion, H 2 concentration and long- * Corresponding author.
