| 摘 要： | 首次采用沉积沉淀法，以Cu（OH）2为前驱体制备不同CuO负载质量分数的CuO/ZnO水煤气变换（WGS）催化剂，并运用XRD、N2物理吸附和TPR等方法对催化剂进行结构表征。结果表明，活性组分CuO在载体ZnO表面的分散程度、颗粒大小及CuO和ZnO之间相互作用对催化剂的活性均有影响。CuO的适宜负载质量分数为20％，所得CuO/ZnO催化剂样品WGS反应活性较好，在350 ℃，CO转化率可达95.5％。

| Abstract: | CuO/ZnO catalysts with different CuO content were prepared by deposition precipitation method for water gas shift reaction, using Cu(OH)2 as the precursor of CuO. The as prepared catalysts were characterized by N2 physisorption, TPR and XRD. The results showed that catalytic activity of the as prepared catalysts was influenced by the dispersion and particles size of CuO as well as the interaction between CuO and ZnO. 20wt%CuO/ZnO catalyst exhibited superior catalytic activity for water gas shift reaction, with CO conversion of 95.5% at 350 ℃. |
