Abstract

Catalytic activity of Pt2+ ion substituted CeO2 synthesized by solution combustion method was tested for low-temperature water gas shift reaction in H2 rich steam reformate. XPS studies show that Pt is dispersed as ions and there is no change in Pt oxidation state after the reaction. CO conversion is found to be maximum at 200 °C over Ce1−xPt x O2−δ catalysts without any methanation. The values of rate are 1.86 and 4.66 μmol/g/s at 125 and 150°C respectively with a dry gas flow rate of 6 Lh−1 over 2% Pt/CeO2.
