Unusual process of water formation on RuO2(110) by hydrogen exposure at room temperature
Article Abstract:
Experimental and theoretical evidence that water forms on the RuO2(001) surface already at room temperature is presented. In a two-step process, hydrogen saturates first the bridging oxygen atoms to form ([O.sub.br]-H) species and subsequently partly of these [O.sub.br]-H groups move to the undercoordinated Ru atoms where they form adsorbed water.

Comment on 'interaction of hydrogen with RuO2(110) surfaces: Activity differences between various oxygen species"
Article Abstract:
A clear-cut experiment with a well-defined stoichiometric RuO2(110) surface is performed demonstrating that Ru-cus atoms are not required for the accommodation of hydrogen on the RuO2(110) surface. Results from many scanning tunneling microscopy (STM) images, estimate an O-cus vacancy density of 1-2 % for this O-saturated RuO2 (110) surface.
