Structure, Morphology, and Catalytic Properties of CuOx/CeO2 Model Catalysts
Cerium dioxide, or ceria, is a chemically stable oxygen ion conducting material with a capacity to store and release oxygen, and is therefore extensively used in combustion catalysts. The Cu-Ce-O system has been identified as one of the most active catalysts for the combustion of carbon monoxide. To study the catalytic oxidation of CO, we have synthesised model CuOx/CeO2 catalysts by gas phase tec
