Abstract

The effect of preparation method on MgO-promoted Ni-Ce_0.8Zr _0.2O₂ catalysts was investigated in CO₂ reforming of CH₄. Co-precipitated Ni-MgO-Ce_0.8Zr _0.2O₂ exhibited very high activity as well as stability (X_CH4 > 95% at 800 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.
