Zusammenfassung:This special issue of The European Physical Journal D contains papers which have been presented at the 12th InternationalSymposium on Small Particles and Inorganic Clusters. ISSPIC-12 was held from September 6th to 10th, 2004, in Nanjing, China.
The influence of modifying additives of Ce, Zr, La and Cs oxides on changes of electronic state of supported copper during the catalytic reaction of butane complete oxidation has been studied by the methods of IR-spectroscopy of adsorbed CO, XPS, EXAFS and XRD. The modifying additions of cerium and zirconium oxides stabilize the ionic state of copper, while lanthanum and cesium oxides decrease the effective charge of copper ions. The observed effects are caused by variation in metal dispersivity in the modified samples and by electron donor-acceptor interaction of the surface atoms and ions of copper with the modifier.
