| 摘 要： | 采用沉积-沉淀法制备了Au负载催化剂。通过对CO在催化剂上的低温催化氧化反应的研究,考察了载体选择,Au的质量分数,金属助剂修饰和反应温度等对反应的影响。结果表明,载体的选择和Au的含量对催化活性都有较大影响,γ-Al2O3是除氧实验中性能优良的催化剂载体材料。使用金属氧化物修饰载体可起到提高催化剂活性,增强催化剂稳定性的作用。 |

| Abstract: | The supported gold catalysts were prepared by deposition -precipitation method. The experiment was investigated for oxidation of CO over supported gold catalysts at a low temperature. The influence of carrier, gold content, metal assistant and reaction temperature was studied. The result shows that the selection of carrier and the gold mass fraction have great effect on the activity of the catalyst. γ-Al2O3 is the best carrer material in this experimentation. Metal oxide as the modify carrier could advance the activity and stability of the catalyst evidently. |
