| 摘 要： | 用电子显微镜（TEM）和程序升温仪（TPR）分别对加钾（K）前后的共沉淀铜钴催化剂m（Cu）／m（Co）=0．358g]进行了TEM和TPR表征．从TPR图上发现，催化剂加K后，催化剂的还原性受到抑制，导致加K后催化剂活性下降；另外从TEM图上得知，加钾后催化剂的粒径增大，也导致加钾后催化剂活性下降，因此催化剂中钾的加入量应适宜．

| Abstract: | Characterization of TEM and TPR for copper-cobalt catalysts has been done in this paper. The reason why the activity decreased, when the element of K is added into copper-cobalt catalyst, has been explained well from its microstructure. |
