To develop a single stage water-gas shift reaction (WGS) catalyst for compact reformers, Pt/CeO2, Pt/ZrO2, and Pt/Ce (1-x)Zr(x)O2 catalysts have been applied for the target reaction. The CeO2/ZrO2 ratio was systematically varied to optimize Pt/Ce(1-x)Zr(x)O 2 catalysts. Pt/CeO2 showed the highest turnover frequency (TOF) and the lowest activation energy (Ea) among the catalysts tested in this study. It has been found that the reduction property of the catalyst is more important than the dispersion for a single stage WGS. Pt/CeO2 catalyst also showed stable catalytic performance. Thus, Pt/CeO2 can be a promising catalyst for a single stage WGS for compact reformers.
