中文摘要：
用XRD、LRS、NH3-TPD、CO2-TPD和CO—FFIR等表征手段考察了不同温度焙烧的氧化锆表面性质的差别，特别是表面酸碱性的差异对Cu／ZrO2催化剂CO加氢反应行为的影响。结果表明，不同温度焙烧的氧化锆表面酸碱性具有较大的差异，其中以450℃焙烧的氧化锆具有较高的表面碱性和最低酸性。这些表面性质的差异对于Cu／ZrO2催化剂的CO吸附行为产生较大的影响，进而影响CO的加氢反应活性。以450℃焙烧的氧化锆为载体时，Cu／ZrO2催化剂具有较好的反应活性。
英文摘要：
The surface properties of zirconia calcined at different temperatures were characterized by XRD, LRS, NH3-TPD, CO2-TPD and CO-FTIR. The effect of zirconia surface properties on the catalytic performance of Cu/ ZrO2 in CO hydrogenation was investigated. The results indicated that the surface properties of zirconia support, especially the surface base-acid properties, are affected significantly by the calcination temperature; the zirconia calcined at 450 ℃ exhibits high basicity and low acidity. The support surface properties also exhibit a great influence on the performance of Cu/ZrO2 catalyst for CO adsorption and CO hydrogenation. An active Cu/ZrO2 catalyst for CO hydrogenation can be obtained with zirconia calcined at 450 ℃ as the support.
