Abstract

A simple auto-redox strategy was successfully used to synthesize Co₃O₄/CeO₂ nanocomposites. These samples 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 Co₃O₄/CeO₂ nanocomposites could be optimized by changing the molar ratio of Co/Ce, pH values, reaction and calcination temperatures. The optimal Co₃O₄/CeO₂ nanocomposite could reach a 100% CO conversion at 140℃ compared to the others. Moreover its catalytic activity kept stable after cycling, indicating its good stability.
