根据CuC_2O_4·H_2O的性质，结合胶体/沉淀理论，提出了一种制备高活性Cu/ZnO基甲醇合成催化剂的实用方法，并进行了实验验证。乙醇溶液中的共沉淀反应是制备高活性、高选择性催化剂的有效途径。通过XRD、N2物理吸附、TEM和N2 O滴定法测定铜的比表面积等手段对催化剂进行了表征，结果表明，制备条件对前驱体和催化剂的结构、表面性质以及CO2加氢合成甲醇的催化活性有重要影响。
According to the features of CuC2O4·H2O and the colloid/precipitation theories, a practical approach for the preparation of Cu/ZnO-based catalyst, which had high activity for methanol synthesis, was proposed and verified in experiments. Co-precipitation reaction in the ethanol solution was found to be an effective route for the preparation of a highly active and selective catalyst. The characterization of XRD, N2physisorption, TEM and the measurement of the copper surface area by nitrous oxide titration revealed that preparation conditions have a significant influence on the structure and surface properties of the precursors and the catalysts, as well as on the catalytic activities for methanol synthesis from CO2hydrogenation.
