Abstract

Noble metals highly dispersed on cerium mixed oxide supports Ce(M)O2−x (M=Zr,Tb) are currently being investigated, not only due to their relationship with the so called Three-Ways Catalysts (TWC) but also because of their potential applications in other catalytic processes related to the hydrogen production or the elimination of organic pollutants in residual waters from different industrial processes [1]. Among these supported noble metals catalysts, Ru containing materials seems to be more stable while at the same time very active and selective in comparison with other supported noble metals [2].
