Fluorescence Detected Surface Exafs (FDSEXAFS) of Iodine on Platinum: An Attempt to the In-situ Structure Determination of an Electrochemical Interface

摘要

Using a grazing incidence geometry, fluorescence detected surface EXAFS has been employed to investigate the structure of iodine adsorbed on platinum (III single crystals. By Fourier analysis of the data a Pt-I distance of 2.46 A is obtained. These results point to the feasibility of employing this technique for the in-situ structural study of electrochemical interfaces.
