abstract
Hydrogen (H
2
) production in a clean and green manner via renewable sources is at present
of great interest. 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-
