The geometry of a bimetallic FeCo site as identified by the EXAFS measurements in the cobalt-iron oxyhydroxides formed through helical borophosphate reconstruction. The CoO bond distance is consistent with the presence of a -oxyl radical.[28]The FeO bond distance is around 6% shorter than in oxidic iron(III) compounds, which could be explained by the oxyl radical character of the oxygen. We hypothesize that such oxyl radical bridged bimetallic species are the active centers for OER catalysis.
