Using the methods of IR spectroscopy of adsorbed CO, electron spectroscopy of diffuse reflectance, XRD, XPS, EXAFS and electron microscopy the influence of modifying additions of Ce, Zr, La and Cs oxides on the surface electronic states of supported gold have been studied. The additions of Ce and Zr oxides stabilize the ionic states of supported gold and increase the effective charge of the ions. In contrast, La and Cs oxides lower the effective charge of gold cation and favor their fast reduction.
