Résumé :

Methane and carbon dioxide activation play a major role in catalysis processes like dry reforming, syngas production and others. Any valorisation of CO2 and CH4 must take into account that they are strong greenhouse gases. CO2 and CH4 are also the main compounds of biogas. The combustion of which is a source of electricity in combined heat-power cogeneration plant (CHP).Our present efforts are devoted to design a catalytic sensor for biogas analysis. In such a sensor , both gases have to be activated at room temperature, which has been demonstrated as possible with cobalt based oxide. However, the deposition of the active phase on a silicon support needs a special attention, in order to provide the highest possible surface to increase the number of active site, while offering the guarantee that the active phase won’t be easily removed during the sensor functioning
