The adsorption of sulfur dioxide, SO2, on graphene, epitaxially grown on Ru(0001) (short Gr/Ru), was studied at ultrahigh vacuum conditions, by thermal desorption spectroscopy, TDS, and Auger electron spectroscopy, AES. TDS detected the parent mass, i.e., a molecular adsorption/desorption pathway was present. However, deviations in the gas-phase fragmentation pattern and multimass TDS were observed. In addition, AES revealed adsorbed sulfur after TDS experiments. Thus, SO2 partially decomposed on Gr/Ru.
