An effective and stable Ni2P/TiO2 catalyst for the hydrogenation of dimethyl oxalate to methyl glycolate

•An effective Ni2P/TiO2 catalyst was proposed for dimethyl oxalate hydrogenation.•A 93.0% conversion of dimethyl oxalate was obtained under 210 °C.•A selectivity of 88.0% to methyl glycolate was achieved under 210 °C.•Ni2P/TiO2 catalyst showed a superior stability which can be performed for 3600 h.

An effective and stable bifunctional Ni2P/TiO2 catalyst was proposed for gas-phase hydrogenation of dimethyl oxalate to corresponding alcohols. A 93.0% conversion of DMO with a selectivity of 88.0% to methyl glycolate was observed under 210 °C. Moreover, the catalyst showed an excellent stability which can be performed for 3600 h under the reaction conditions of 230 °C, 3 MPa H2 and the weight space velocity of 0.1 h− 1.
