Binder-free quaternary Ni-Fe-W-Mo alloy as a highly efficient electrocatalyst for oxygen evolution reaction

摘要

Constructing highly efficient electrocatalyst for oxygen evolution reaction (OER) is essential for the development of electrocatalytic water splitting. Herein, a binder-free and quaternary Ni-Fe-W-Mo alloy nanostructure was constructed by the electrodeposition strategy, and the electrocatalytic performances at the room and high temperatures (80 degrees C) were also investigated in the alkaline electrolyte. Owing to the synergistic effect of alloying and the self-supportive configuration, the binder-free Ni-Fe-W-Mo alloy showed the small overpotential and superior stability for OER at the room and high temperatures. This work may provide a new chance for constructing efficient OER electrocatalysts for energy conversion applications. (C) 2020 Elsevier B.V. All rights reserved.
