Activating gold : High‐resolution photoemission spectroscopy and DFT calculations were used to study the interaction of SO 2 with Au/TiC(001) surfaces. Both revealed molecular adsorption of SO 2 on TiC(001) but complete dissociation of the SO bonds on Au/TiC(001) (see picture). Au/TiC(001) cleaves SO bonds more efficiently than Au/TiO 2 (110) or Au/MgO(100) and decomposes SO 2 at temperatures as low as 150 K.
