Low temperature water-gas shift (WGS) reaction has been carried out at the gas hourly space velocity of 72,152 h-1 over Cu-CeO2 catalyst prepared by a co-precipitation method. Cu loading was optimized to obtain highly active co-precipitated Cu-CeO2 catalysts for low temperature WGS. 80 wt% Cu-CeO2 exhibited the highest CO conversion as well as the most stable activity (XCO > 46% at 240 °C for 100 h). The excellent catalytic performance is mainly due to a strong metal to support interaction, resulting in the prevention of Cu sintering.
