Single stage water-gas shift reaction has been carried out at a gas hourly space velocity of 45,515 h-1 over supported Pt catalysts prepared by an incipient wetness impregnation method. CeO2, ZrO2, MgO, MgO-Al2O3 (MgO = 30 wt%) and Al2O3 were employed as supports for the target reaction in this study. 1 wt% Pt/CeO2 exhibited the highest CO conversion as well as very high CO2 selectivity due to high oxygen storage capacity of CeO 2.
