【 摘 要 】

The work is focused on the investigation of the influence of metal oxide promoted ceria based materials with various dopants on the physicochemical, electrical and catalytic properties for CO oxidation in model reaction. The formation of stable solid solutions by doping copper, manganese, zirconium, gadolinium, and bismuth enhances the redox properties, oxygen vacancies, stability, and, of course, catalytic activity and electroconductivity.
