6. 4. Water-Metal Surfaces : Insights from core-level spectroscopy and density functional theory

   Author : Theanne Schiros; Anders Nilsson; John Hemminger; Stockholms universitet; []
   Keywords : water; hydroxyl; metal; surfaces; x-ray spectroscopy; density functional theory; bonding; fuel cell; kemisk fysik; Chemical Physics;

   Abstract : Computational methods are combined with synchrotron-based techniques to analyze the structure and bonding of water and water plus hydroxyl at metal surfaces under UHV and at near-ambient conditions. Water-metal interaction plays a crucial role in a multitude of cosmic, atmospheric and biological phenomena as well as heterogeneous catalysis, electrochemistry and corrosion. READ MORE
