- Water gas shift reaction (WGS) over Cu-Mo/CexZr1-xO₂ catalysts was investigated to develop an alternative to commercial Cu-ZnO/Al₂O₃(LTS) catalyst. Mixed oxides (CexZr1-xO₂(x=0.3-0.9)) were prepared and used as supports of Cu-Mo bimetallic catalysts. The catalysts prepared by co-precipitation and impregnation methods were characterized by N₂physisorption. CO chemisorption, TPR, XRD and TEM techniques. It was found that 12wt%Cu-2wt%Mo/Ce₀.₅Zr₀.₅O₂catalyst showed higher activity and thermal stability than the commercial LTS catalyst for WGS reaction during the thermal cycling reaction under the tested conditions.
