摘　　要：ZrO2具有弱酸碱性、氧化还原性、良好的热稳定性和机械强度,在催化领域得到广泛应用。以Zr O2为载体的铜基催化剂因其活性高,选择性好,性能稳定,受到越来越多的关注。本文介绍了Cu/Zr O2催化剂在醇类的水蒸气重整制氢、CO/CO2加氢合成低碳醇、二乙醇胺脱氢、乙醇直接合成乙酸乙酯和低温水煤气变换方面的应用。综述了添加不同助剂对Cu/Zr O2催化剂物化及催化性能的影响。Zr O2 is widely used as active catalyst owing to its peculiar characteristics,such as weak acidity and basicity,redox properties,high thermal and mechanical stability. Cu / Zr O2 catalysts have attracted increasing attention due to their high activity,selectivity and performance stability. The applications of the Cu / Zr O2 catalysts in the production of hydrogen from steam reforming of alcohols,synthesis of methanol from hydrogenation of CO and / or CO2,diethanolamine dehydrogenation,direct transformation of ethanol to ethyl acetate and water-gas-shift reaction at low temperatures are introduced. The effects of different promoters on the physiochemical and catalytic properties of Cu / Zr O2 catalysts are summarized.
