本文采用（NH4）2Ce（NO3）6和Cu（NO3）2为原料，通过浸渍法制备了不同铜负载量的CuO/CeO2水煤气变换催化剂，利用XRD、BET、TPR等对所合成样品进行了表征，并考察了其水煤气变换反应催化性能。结果表明，铜负载量对CuO/CeO2催化剂的结构与性能影响较大，适宜的铜负载量有利于提高CuO/CeO2催化剂的水煤气变换反应活性，浸渍法制备的CuO/CeO2催化剂最佳铜负载量为12％，较高的铜负载量（14-16％）形成的晶相氧化铜对CuO/CeO2催化剂的活性有抑制作用。

The CuO/CeO2 water gas shift catalysts with different copper loadings were prepared by impregnation from ( NH4 ) 2 Ce ( NO3 ) 6 and Cu ( NO3 ) 2 as starting materials , The as -synthesized samples were tested for the water -gas shift reaction and characterized by XRD ,TPR/STPR,TPD.The results show that Copper loadings are an important factor to affect the structure and properties of CuO /CeO2 catalyst .The appropriate loaded amount of copper help to improve catalytic activity for water gas shift reaction , and the best copper loadings are 12%.the higher copper loading ( 14-16%) would formed crystalline phase of copper oxide which inhibited the catalytic activity of CuO/CeO2 catalyst .
