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.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.
