In this work, we present the elaboration of nanostructured powders of cerium dioxide (Ce02.z) and ruthenium dioxide Ru02 by sol gel wute and their catalytic activities in presence of air methane mixtures. Prom Fourier transform infrared spectroscopy, the conversion rate of CH4 into C02 and H20 was determined as function of time. Nanostructured powders of Ce02 and Ru02 presented very different activities in presence of air-CH4 flows. We propose a semi-empirical Avrami' s approach of catalytic kinetics for these two different systems exposed to gas reduction during long times.
