Abstract

Na promoted Pt/TiO2 catalysts have been studied under high severity, near equilibrium, conditions for use as a single stage WGS catalyst. Addition of 3 wt% Na to a 1 wt% Pt/TiO2 catalyst has been found to improve water gas shift activity significantly compared to Pt/TiO2, Pt/CeO2, and Pt–Re/TiO2 catalysts. This catalyst is stable when the reaction temperature is higher than 250 °C. Deactivation occurred when the reaction temperature was lower than 250 °C, however, returning the temperature to higher than 250 °C fully recovered activity. TEM observations revealed that addition of Na inhibited Pt particle sintering. These results suggest that Na promoted Pt/TiO2 is a promising single stage water gas shift catalyst for small scale hydrogen production.
