Iron-doped ceria solids were synthesized through the citrate route. The incorporation of iron in the structure of ceria produced changes in the shape of the crystallites constituting the solid particles and the pore structure, improved the reducibility and enhanced the catalytic performance of the samples in the conversion of methane in diluted conditions. The solid with nominal composition Ce0.9Fe0.1O1.95 was the most active catalyst in the oxidation of diluted methane streams, achieving 55% of methane conversion at 700 degrees C.
