Plasma-enhanced copper dispersion and activity performance of Cu-Ni/ZrO2 catalyst for dimethyl oxalate hydrogenation

An efficient plasma-treated method of Cu-Ni/ZrO2 catalyst was prepared via the depositionâ??precipitation method for the selective hydrogenation of dimethyl oxalate (DMO) to ethylene glycol (EG). Compared with the untreated sample, the plasma- treated Cu-Ni/ZrO2 catalyst exhibited enhanced Cu dispersion and significantly improved selectivity to EG and stability for long time on stream. An ethylene glycol selectivity of higher than 95% was obtained after 150h of reaction. XRD and TEM measurements revealed that the mean copper particle size of the catalyst was remarkably reduced by plasma pretreatment. TPR and XPS measurements also indicated that copper dispersion was improved.
