Nickel-magnesia solid solution catalyst with low Ni content had excellent stability for methane reforming with carbon dioxide at 1123 K without the formation of carbon deposition. Nickel-magnesia solid solution and magnesia supported nickel catalysts were characterized by means of FTIR, TEM, and the amount of H2 and O2 adsorption. Ni metal particles on Ni0.03Mg0.97O have considerably high dispersion and the interaction with support surface. It is suggested that high resistance to carbon deposition is caused by supplying CO2 or oxygen species through the interface between nickel metal and support surface.
