    • Intermediates and Spectators in O2 Dissociation at the RuO2(110) Surface

      Hangyao Wang, William F. Schneider and David Schmidt
      The Journal of Physical Chemistry C2009 113 (34), 15266-15273

      Using plane wave DFT calculations, we identify various configurations of peroxo-like and superoxo-like molecular oxygen adsorbed at the RuO2(110) surface. All configurations are found to be metastable to dissociative oxygen adsorption in the presence of ...

    • Novel Insight in the CO Oxidation on RuO2(110) by in Situ Reflection−Absorption Infrared Spectroscopy

      A. Farkas, G. Ch. Mellau and H. Over
      The Journal of Physical Chemistry C2009 113 (32), 14341-14355

      In situ reflection−absorption infrared spectroscopy (RAIRS) experiments identify the most abundant surface species during the CO oxidation on RuO2(110) in a wide pressure range from 10−7 mbar to 10−3 mbar. Under reaction conditions with highest catalytic ...

    • Complex Interaction of Hydrogen with the RuO2(110) Surface

      M. Knapp, D. Crihan, A. P. Seitsonen, E. Lundgren, A. Resta, J. N. Andersen, and H. Over
      The Journal of Physical Chemistry C2007 111 (14), 5363-5373

      Using a variety of dedicated surface sensitive techniques, we studied the interaction of hydrogen with bare and adsorbate modified RuO2(110) surfaces on the atomic scale. Hydrogen interacts strongly with the undercoordinated O atoms, thereby forming ...

    The Journal of Physical Chemistry C2007 111 (5), 2242-2250
    • Scanning Tunneling Microscopy of the RuO2(110) Surface at Ambient Oxygen Pressure

      M. Rössler, S. Günther, and J. Wintterlin
      The Journal of Physical Chemistry C2007 111 (5), 2242-2250

      To test predictions about the activity of Ru catalysts the RuO2(110) surface was investigated in an oxygen atmosphere at ambient pressure using scanning tunneling microscopy (STM). Epitaxial RuO2(110) films were grown on a Ru(0001) sample following an ...

    • Hydrogen Transfer Reaction on the Surface of an Oxide Catalyst

      Marcus Knapp, Daniela Crihan, Ari P. Seitsonen, and Herbert Over
      Journal of the American Chemical Society2005 127 (10), 3236-3237

      RuO2(110) exposes two kinds of active surface species (acidic and basic centers) that govern the interaction of the gas phase in contact with the catalyst's surface. Here we will elucidate the cooperative interplay of these two active surface sites for a ...
