The effect of preparation method on MgO-promoted Ni-Ce0.8Zr0.2O2 catalysts was investigated in CO2 reforming of CH4. Co-precipitated Ni-MgO-Ce0.8Zro.2O2 exhibited very high activity as well as stability (X-CH4 > 95% at 800 degrees C for 200 h) due to high surface area, high dispersion of Ni, small Ni crystallite size, and easier reducibility. Four elements (Ni, Mg, Ce, and Zr) are located at the same position for the co-precipitated catalyst, resulting in easier reducibility. Copyright (C) 2013, Hydrogen Energy Publications, LLC.
