摘要
采用ＸＰＳ、ＴＥＭ、ＩＣＰ、ＸＲＤ、ＴＧ、ＤＴＡ、ＴＰＤ、ＩＲ等方法对一组工业用ＣｕＯ／ＺｎＯ／Ａｌ＿２Ｏ－３催化剂试样的元素、物相及表面组成进行系统分析，并借助热分析技术考察试样分解过程，结果表明该组催化剂性质上的差异与指定约合反应的催化活性相有关。
A serles of Cu/Zn/Al industrial catalysts skowing different catalytic actions have beensystematically characterized by XPS,TEM,ICP,XRD,DTA,IR,in regard to theirelemental colnposition,surface compositiOn,chemical phases and other properties.The decom-position kinetics of these catalysts has also been studied by the thermal analysis techniques;theresults show that correlationship exists between these properties and the catalytic activitiesof the given reaction.
