The activity aims at preparation, physicochemical characterization (including evaluation of the reduction behavior by quantitative and also qualitative results from temperature programmed reduction measurements) and catalytic activity tests of nanosized gold catalysts on ceria and modified with other metals ceria supports. The goal is: i) the understanding of relationship between structure of the doped ceria supports, reducibility depending on the presence of gold and doping metals and the catalytic behavior; 2) the selection of highly active, selective and stabile gold catalysts on appropriate metal oxide supports for important from the environmental point of view reactions as pure hydrogen production via water gas shift (WGS) and selective oxidation in hydrogen reach steam (PROX), and air pollution abatement via hydrocarbon complete oxidation.
