Auto-redox Strategy for the Synthesis of Co3 O4 /CeO2 Nanocomposites and Their Structural Optimization Towards Catalytic CO Oxidation
摘要
Abstract
A simple auto-redox strategy was successfully used to synthesize Co3O4/CeO2 nanocomposites. These sam-ples were then characterized by means of TEM, XRD, XPS, and so on, to study the influence of reaction parameters on their catalyst activity. The results indicate that the catalytic performance of Co3 O4/CeO2 nanocomposites could be optimized by changing the molar ratio of Co/Ce, pH values, reaction and calcination temperatures. The optimal Co3 O4/CeO2 nanocomposite could reach a 100％ CO conversion at 140℃ compared to the others. Moreover its cata-lytic activity kept stable after cycling, indicating its good stability.关键词
