Regine Streber, Christian Papp, Michael P. A. Lorenz, Andreas Bayer, Reinhard Denecke and Hans-Peter Steinrück Sulfur Oxidation on Pt(355): It Is the Steps! Angewandte Chemie International Edition 48
Steps in the right direction: The role of steps in the removal of sulfur from a Pt model catalyst, via metastable SO3 and SO4 species, was demonstrated by in situ high-resolution X-ray photoelectron spectroscopy. From isothermal experiments the activation energy of the rate-determining step was deduced to be 34 kJ mol−1.
