Abstract

The electronic states of gold in gold supported nanoparticles modified by Ce, Zr, La and Cs oxides have been studied by the methods of IR spectroscopy of adsorbed CO, UV-visible spectroscopy of diffuse reflectance. XRD and electron microscopy. The additives 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 ion effective charge and favour their fast reduction under redox treatments and reaction medium. It is explained by electron donor-acceptor interaction of the supported metal nanoparticles with the modifiers.
