Many transition metals and alloys are expected to have high catalytic activities because of incompletely filled d orbitals for readily giving and taking electrons. However, the poor corrosion resistance, originating from high chemical activity, limits their applications as electrocatalysts for reactions in acidic and alkaline electrolytes. In this study, it is found that homogeneous amorphous structure can effectively decouple the intertangling catalytic activities and electrochemical stability of transition metal alloys. A noble-metal-free Ni40Fe40P20 metallic glass shows superior catalytic activities and high corrosion resistance, in comparison with the crystallized counterpart and other nanostructured noble-metal-based catalysts, for electrochemical water splitting in both acidic and alkaline solutions.
