Hydrogen adsorption on RuO₂(110) — •Bianca Eifert¹, Christian Heiliger¹, Jan Philipp Hofmann², Herbert Over², and Ari Paavo Seitsonen³ — ¹Physikalisches Institut, Justus Liebig University Giessen, D-35392, Germany — ²Physikalisch-Chemisches Institut, Justus Liebig University Giessen, D-35392, Germany — ³Physikalisch-Chemisches Institut, University of Zurich, CH-8057, Switzerland

Complementary to experimental work, density functional theory calculations are utilized to gain a deeper insight into the adsorption and insertion behavior of hydrogen and water species on the RuO₂(110) surface at an atomic level. This is important for an improved understanding of RuO₂ as a model and real catalyst system in reactions spanning from oxide-catalyzed dehydrogenation to a wide range of electrochemical reactions.
