Abstract: ZrO_2-Al_2O_3 composite oxides and supported Ni catalysts were prepared, and characterized by N_2 adsorption/desorption, X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) techniques. The catalytic performance and carbon deposition was also investigated. This mesoporous composite oxide is shown to be a promising catalyst support. An increase in the catalytic activity and stability of methane and carbon dioxide reforming reaction was resulted from the zirconia addition, especially at 5wt% ZrO_2 content. The Ni catalyst supported ZrO_2-Al_2O_3 has a strong resistance to sintering and the carbon deposition in a relatively long-term reaction.
