Abstract

Abstract Designing highly active and stable electrocatalysts for oxygen evolution reaction (OER) is the key to success in sustainable water splitting reaction, a sustainable route towards high purity hydrogen production. Interface engineering is one of the most effective strategies for modulating the local electronic structure of active sites to enhance catalytic activity. Herein, NiFe2O4−x nanoparticles were integrated to NiMoO4 nanowires (NiFe2O4−x/NMO) grown on nickel foam to construct an extended interface with strong electronic interactions. The NiFe2O4−x/NMO demonstrates high OER activities as manifested by a low overpotential of 326 mV at a high current density of 600 mA cm−2 and good long-term stability. The intimate interface between NiFe2O4−x and NiMoO4 is responsible for the Fe-facilitated phase transition to active γ-NiOOH phase as revealed by in situ Raman spectroelectrochemical studies. This study outlines how the interface design of integrated nanostructures can optimize the formation of active phase for enhanced catalytic activity.

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.
