The chemical state of adsorbed sulfur (S) on a Pt surface was identified and investigated by a combination of detailed electrochemical (EC) measurements, in situ surface enhanced Raman scattering (SERS) and ab initio density functional theory (DFT) calculations. The SERS data of the adsorbed S coupled with the DFT calculations provide the first convincing evidence showing that the adsorbed sulfur is in a sulfide (S 2− ) state.
