Iron tungsten mixed composite as a robust oxygen evolution electrocatalyst

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 FeO x is the OER-active site and the neighboring WO x improves the *OH to *...

Description
Summary: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 FeO x is the OER-active site and the neighboring WO x improves the *OH to *O conversion on the Fe site. An iron tungsten mixed composite exhibited a high activity and a long-term stability for oxygen evolution reaction electrocatalysis.
