High-Performance Transition Metal Phosphide Alloy Catalyst for Oxygen Evolution Reaction
Open accessAbstract
Oxygen evolution reaction (OER) is a pivotal process in many energy conversion and storage techniques, such as water splitting, regenerative fuel cells, and rechargeable metal-air batteries. The synthesis of stable, efficient, non-noble metal-based electrocatalysts for OER has been a long-standing challenge. In this work, a facile and scalable method to synthesize hollow and conductive iron–cobalt phosphide (Fe–Co–P) alloy nanostructures using an Fe–Co metal organic complex as a precursor is described. The Fe–Co–P alloy exhibits excellent OER activity with a specific current density of 10 mA/cm 2 being achieved at an overpotential as low as 252 mV. The current density at 1.5 V ( vs reversible hydrogen electrode) of the Fe–Co–P catalyst is 30.7 mA/cm 2, which is more than 3 orders of magnitude greater than that obtained with state-of-the-art Fe–Co oxide catalysts. Our mechanistic experiments and theoretical analysis suggest that the electrochemical-induced high-valent iron stabilizes the cobalt in a low-valent state, leading to the simultaneous enhancement of activity and stability of the OER catalyst.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
