Adsorption modes of acetylene on Pt-Sn alloys have been identified at the molecular level for the first time by consolidating HREELS and TPD experimental results with DFT calculations. The presence of Sn changes preferential hydrocarbon adsorption sites, decreases stability of adsorbed species and favors associative reactions, thus, enabling benzene production.
