Optimizing the surface state of cobalt-iron bimetallic phosphide regulating phosphorus vacancies

Herein, we successfully regulated phosphorus vacancies in Co 0.68 Fe 0.32 P through Ar-plasma treatment. The Ar-plasma treated Co 0.68 Fe 0.32 P exhibits a delicate surface state where the surface Co and Fe ions show an unusual electron loss. The unique surface state enhances the oxygen evolving per...

Zusammenfassung:Herein, we successfully regulated phosphorus vacancies in Co 0.68 Fe 0.32 P through Ar-plasma treatment. The Ar-plasma treated Co 0.68 Fe 0.32 P exhibits a delicate surface state where the surface Co and Fe ions show an unusual electron loss. The unique surface state enhances the oxygen evolving performance of the phosphide. We regulated phosphorus vacancies in Co 0.68 Fe 0.32 P by Ar-plasma treatment, leading to a unique surface state.
