文摘

CeO₂ and Au-CeO₂ thin films with different thickness were deposited on the carbon nanotubes by using magnetron sputtering of cerium dioxide and gold. The catalyst films were tested using scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). XPS showed that thickness has significant influence on CeO₂ films stoichiometry and in turn ceria stoichiometry influences gold oxidation states in Au doped CeO₂ catalyst.
