Abstract

We report a FeW mixed composite for oxygen evolution reaction with a low overpotential and a long-term stability. A structural transformation of FeW oxide occurs during the OER process. Theoretical calculation indicates that FeOx is the OER-active site and the neighboring WOx improves the *OH to *O conversion on the Fe site.
