| 摘要 | Herein, the Cu species uniformly combining with highly crystalline ZrO2 nanosheets had been prepared by a one-pot acetic complex method. The selectivity to ethylene glycol of 98.9%, which corresponds to 99.8% conversion of diethyl oxalate was obtained over the one prepared by using acetic acid (AC) both as the complex agent and solvent. In addition, a stable performance was achieved (life span of >160 h). It also showed good performance in hydrogenation of dimethyl oxalate (95.7 h(-1) turnover frequency). Essentially, solvents with different dielectric constant employed in complexation process had a prominent influence on the structure and catalytic activity of Cu/ZrO2 catalyst via solvation. Besides, complexation process was also important since AC could be regarded as L-type ligands in a low dielectric constant solvent, forming of ion-clusters which resulted in exclusive formation of the Cu-O-Zr interface after calcination. Evidently, the surface synergistic effect held the key to the continuous hydrogenation reaction related to the activation of the carbonyl groups and the hydrogen dissociation, thus creating a synergetic nanoenvironment for the successful completion of the "multi step turning into one-step" in the series reaction.
