摘要： 采用溶胶凝胶法制备了高性能纳米Cu/SiO2催化剂，并将其应用于芳香酮的加氢反应。采用ICP、XRD、H2-TPR、TEM、N2物理吸附和XPS等手段对催化剂进行了表征分析。比较了催化剂制备方式对加氢反应的影响。同时对芳香酮的加氢反应工艺条件进行了探究，结果表明：在最佳反应条件下，苯乙酮基本完全转化。采用溶胶凝胶法制备的Cu/SiO2催化剂相较于共沉淀法，具有更小的颗粒粒径，活性物种分散性良好。最后对反应的苯乙酮加氢机理进行了探究，Cu0和Cu+的协同作用提高了催化剂的活性和稳定性。

Abstract: In this paper, high performance nano Cu/SiO2 catalyst was prepared by sol-gel method for hydrogenation of aromatic ketones. The catalyst was characterized by ICP, XRD, H2-TPR, TEM, N2-adsorption and XPS. The influence of preparation method of Cu/SiO2 catalysts on hydrogenation performance of acetophenone was investigated. The results showed that Cu/SiO2 catalyst prepared by sol-gel method had small particle size and good dispersion of active species compared with the co-precipitation method. The acetophenone was almost completely transformed under the optimal conditions. Besides, the hydrogenation mechanism of acetophenone was further studied. It was found that the synergistic effect of Cu0 and Cu+ improved the activity and stability of the catalyst.
Key words: Cu/SiO2 catalyst; preparation method; hydrogenation of acetophenone; reaction mechanism
