Ag-Fe复合氧化物催化剂的结构及还原性能
摘要:
采用共沉淀法制备了Ag-Fe复合氧化物催化剂.用XRD研究了不同Ag含量催化剂的结构变化情况,利用程序升温还原技术(TPR)考察了热处理温度对催化剂还原性能的影响.结果表明:不同Ag含量催化剂的还原能力与σ-AgFeO2晶相生成情况有对应关系,催化剂的氧活性主要来源于分散在其表面晶粒较小的σ-AgFeO2物种.

Structure and Reductive Characteristics of Ag-Fe Complex Oxide Catalysts
Abstract:
Ag-Fe complex oxide catalysts were prepared by a coprecipitation method. The structure of the catalysts has been investigated by XRD technique and the effect of thermal treatment on the reducibility of the catalysts by TPR technique. The results show ed that there is a relationship between the reducibilities and Ag contents of the catalysts and the oxidation activities of the catalysts lie in the σ-AgFeO2 species dispersed on the surface of the catalysts.
