Facile synthesis of iron phosphide nanorods for efficient and durable electrochemical oxygen evolution

Iron phosphide (FeP) nanorods have been fabricated by a facile hydrothermal synthesis of iron oxyhydroxide precursors, followed by a convenient phosphorization process. The FeP nanorods dispersed on carbon fiber paper current collectors exhibit outstanding catalytic activity and excellent long-term stability toward the oxygen evolution reaction (OER).
