A Ni-foam-structured MoNi4–MoOx nanocomposite catalyst for hydrogenation of dimethyl oxalate to ethanol

Author affiliations

Abstract

We report a Ni-foam-structured MoNi4–MoOx nanocomposite catalyst derived from NiMoO4 spinel in situ grown on Ni-foam, which is highly active, selective (>93%) and stable for the gas-phase hydrogenation of dimethyl oxalate to ethanol. Such a reaction proceeds mainly through ethylene glycol formation, whereas a pathway through methyl acetate (MA) formation also occurs. Catalyst activity and selectivity are primarily governed by the MoNi4 nanoalloy but can be further improved by an MoOx modifier, due to the synergistic MoNi4–MoOx interaction that markedly promotes the MA hydrogenation to EtOH.
