Cu/MnOx-CeO2 and Ni/MnOx-CeO2 catalysts for the water-gas shift reaction: Metal-support interaction
Monometallic copper and nickel catalysts supported on cerium-manganese mixed oxides are prepared, characterized and evaluated for the Water-Gas Shift (WGS) reaction. Active metal loading of 2.5 wt% and 7.5 wt% are used to impregnate MnOx-CeO2 supports with 30% and 50% Mn:Ce molar ratio. The structur...
