DOIAbstract
High-resolution core-level shift spectroscopy and temperature-programmed reaction experiments together with density functional theory calculations reveal that the oxidation of HCl with oxygen producing Cl2 and water proceeds on the chlorine-stabilized RuO2(110) surface via a one-dimensional Langmuir-Hinshelwood mechanism. The recombination of two adjacent chlorine atoms on the catalyst’s surface constitutes the rate-determining step in this novel Deacon-like process
