Solvothermal preparation of CuO-ZnO-ZrO₂ (CZZ) was realized using ethylene glycol as a solvent. The effects of solvothermal temperature (140–200 °C) on the properties of catalysts and catalytic performance in CO₂ hydrogenation were studied. ICP-OES, N₂ sorption, XRD, SEM-EDX, reactive N₂O adsorption, XPS, H₂-TPR, H₂-TPD, and CO₂-TPD were used as characterization tools. The data indicate that the CZZ-180 catalyst prepared at a solvothermal temperature of 180 °C has the smallest Cu crystallites and the largest surface area of Cu⁰, thus exhibiting the highest methanol yield. The effects of reaction temperature, pressure, and space velocity were also investigated.

以乙二醇为溶剂，实现了溶剂热法制备CuO-ZnO-ZrO ₂（CZZ）。研究了溶剂热温度（140–200°C）对催化剂性能和CO ₂加氢催化性能的影响。ICP-OES，N ₂吸附，XRD，SEM-EDX，反应性N ₂ O吸附，XPS，H ₂ -TPR，H ₂ -TPD和CO ₂ -TPD被用作表征工具。数据表明，在溶剂热温度为180°C下制备的CZZ-180催化剂具有最小的Cu微晶和最大的Cu ⁰表面积。，因此显示出最高的甲醇收率。还研究了反应温度，压力和空速的影响。
