Feasibility analysis of water gas shift reaction for the removal of trace CO in hydrogen

Different metal (Mn, Fe, Co, Ni, and Zr) decorated Cu/CeO2 catalysts for efficient CO oxidation in a rich CO2/H2 atmosphere

“…[5][6][7][8][9] To avoid damage to the Pt electrode, the CO in the reforming gas must be reduced to below 10 ppm. 10,11 CO-Prox was considered as one of the most cost-effective and promising methods to remove CO from hydrogen rich gases. [12][13][14] Among CO-Prox related catalysts, the CuO-CeO 2 catalyst was widely considered because of its low price and high catalytic performance, 15,16 but its catalytic activity and selectivity still have room for improvement.…”
