In this work we present a study on the methane oxidation reaction on Cr2O3 in the presence of sulfur dioxide using both infrared spectroscopy and simulations based on the density functional theory. The purpose of the work is to know the reasons why sulfur dioxide decreases the activation energy of the methane oxidation reaction. We found that sulfur dioxide promotes oxygen dissociation through the formation of sulfite species. Dissociated oxygen favors the dehydrogenation of methane, the formation of methoxy species, formaldehyde, dioxymethylene, and methanol.
