Impact of cobalt oxide morphology on the thermal response to methane examined by thermal analysis

In the present talk, we will demonstrate the impact of particle size and morphology of a metal oxide catalyst on its catalytic ability towards methane oxidation examined in a wide temperature range at dry environmental conditions. The investigations were performed by differential thermal analysis (DTA) technique delivering the thermal response of different cobalt oxide samples differing in particle size. The obtained results demonstrate the reliability of the method for preselection of catalysts for their application in catalytic gas sensors by the example of cobalt oxide, which is a promising catalyst for methane oxidation.
