This unique discussion meeting will bring electrochemists, surface scientists and theoreticians together and foster the development of both in situ spectroscopic methods in electrochemistry and theoretical methods which model the electrocatalytic interface. This unique discussion meeting will bring electrochemists, surface scientists and theoreticians together and foster the development of both in situ spectroscopic methods in electrochemistry and theoretical methods which model the electrocatalytic interface. It will be opened with an introductory lecture by Marc Koper from Leiden University in the Netherlands. Discussion sessions: Structure in Electrocatalysis: from nanoparticles to single crystals Spectroscopy and Electrocatalysis Hydrogen oxidation and oxygen reduction Biological electrocatalysis and alcohols as fuels
