采用溶胶-凝胶法和共沉淀法合成了CuO-ZnO-Al2O3催化剂。然后用其他载体代替Al2O3，如ZrO2、CeO2和CeO2-ZrO2，以便更好地了解载体的效果。这些催化剂含有30 wt%的铜，然后测试二氧化碳加氢成甲醇。研究了反应温度和温室气体浓度对催化性能的影响。结果表明，共沉淀法合成的30 CuO-ZnO-ZrO2催化剂在400℃下煅烧，CO2转化率为23%，甲醇选择性为33%，在280℃、50 bar条件下，甲醇产率为331 g(MeOH).kg(cata)(-1).h(-1)， GHSV为10,000 h（-1）。(C) 2015年中国科学院。Elsevier Masson SAS出版。版权所有。
CuO-ZnO-Al2O3 catalysts were synthesized by two methods, sol-gel and co-precipitation syntheses. Al2O3 was then substituted with other supports, such as ZrO2, CeO2 and CeO2-ZrO2 in order to have a better understanding of the support's effect. These catalysts containing 30 wt% of Cu were then tested for CO2 hydrogenation into methanol. The effect of reaction temperature and GHSV on the catalytic behaviour was also investigated. The best results were obtained with a 30 CuO-ZnO-ZrO2 catalyst synthesized by co-precipitation and calcined at 400 degrees C. This catalyst presents a good CO2 conversion rate (23%) with 33% of methanol selectivity, leading to a methanol productivity of 331 g(MeOH).kg(cata)(-1).h(-1) at 280 degrees C under 50 bar and a GHSV of 10,000 h(-1).
