제목 Water Gas Shift Reaction overCu-Mo/CexZr1-xO2 Catalysts for Fuel Processorand Hydrogen Station Applications
초록 mixed oxides ( CexZr1-xO2 (x = 0.3-0.9))were prepared and used as supports of Cu-Mo bimetallic catalysts. The catalystsprepared by co-precipitation and impregnation methods were characterized by N2 physisorption, CO chemisorption, TPR, XRD and TEM techniques. Water gas shift reaction (WGS) over Cu-Mo/CexZr1-xO2 catalysts was investigatedto develop an alternative to commercial Cu-ZnO/Al2O3(LTS) catalyst. It was found that 12wt%Cu-2wt%Mo/Ce0.5Zr0.5O2 catalyst showed higher activity and thermal stability than the commercial LTS catalyst for WGS reaction during the thermal cycling reaction under the tested conditions.
