The development of active and selective catalysts form methane partial oxidation is one of today´s challenges , because these catalysts could be either for hydrogen production purposes or as anode materials in single-chamber solid oxide fuel cells (SOFCs). In this work , the synthesis of ceria-zirconia solid solutions of nominal composition Co0.9Zr0.1O2 through the gel combustion route is presented. The solids obtained were impregnated with nickel solutions to achieve contents of 9% and 50% (m/m) characterized texturally and structuraly, and their catlaytic behavior in the methane partial oxidation reaction was assessed. The synthesis method was effective, leading to solids with good morphological properites. Likewise , te Ni/Ce0.9r0.1O2 catalysts proved to be active and showed a stable behavior during the working period, with metahne conversion levels of 90% at temperatures above 550C , being hydrogen and carbon monoxide the main products.
