| 摘 要： | 通过共沉淀法制备了不同配比的Ni-Cu催化剂，并采用XRD、TPR和XPS表征方法研究了镍铜相互作用对苯甲醇的催化氧化性能的影响。结果显示，当催化剂体系中只有Ni时，催化剂组分为Ni(OH)2;当催化剂体系含有Ni和Cu时，催化剂组分为Ni(OH)2和Cu(OH)2混合晶相;当催化剂体系中仅含Cu时，催化剂组分为CuO;并且由于镍、铜的相互作用，催化剂的还原温度降低，Ni的存在阻止了Cu(OH)2晶相转变为CuO。此外，催化剂体系中Ni含量越高，其催化活性也越高，Ni的存在提高了Cu的催化性能。

| Abstract: | Ni-Cu catalysts with different ratios were prepared through the precipitation method.The influence of Ni-Cu interaction on the catalytic oxidation of benzyl alcohol was studied with XRD,TPR and XPS characterizations.The result showed that the obtained catalysts were Ni(OH)2,the mixture of Ni(OH)2 and Cu(OH)2,and CuO respectively when the catalyst system contains only Ni,Ni and Cu,and only Cu.The reduction temperature of the catalyst decreased owing to Ni-Cu interaction,and Ni prevented the transformation of Cu(OH)2 to CuO.In addition,the catalytic activity was higher with a higher Ni content and the existence of Ni improved the catalytic activity of Cu. |
