Abstract：A series of mesoporous SiO2 supported Cu catalysts prepared by deposition precipitation method were investigated to research the textural structure effect on the catalytic performance for hydrogenation of dimethyl oxalate (DMO) to ethylene glycol (EG). The 100% DMO conversion and 95% selectivity can be obtained under the copper-containing catalyst synthesized by SBA-15 with regular two-dimensional hexagonal pore structure as support. XRD, BET, H2-TPR, N2O titration and XPS were used to characterize the intrinsic essence of the catalyst. It is suggested that the dispersion of copper species and the interaction between the copper species and the silica are closely related to the textural structure and play a crucial role in the hydrogenation of DMO to EG.
