Enhanced oxygen evolution activity by NiOxand Ni(OH)2nanoparticles
Open accessAbstract
Small nanoparticles of nickel oxide and nickel hydroxide were investigated for the oxygen evolution reaction (OER) in alkaline solutions. These nanoparticles showed excellent catalytic activity, giving a current density of 10 mA cm(-2) at overpotentials (η) of 300 and 330 mV for Ni(OH)(2) and NiO(x), respectively. The catalytic activity was comparable to that of the best mixed metal oxide catalysts under the same conditions. The activity was significantly higher than that of electrochemically formed Ni(OH)(2) and NiO(x) films, demonstrating the benefit of nanostructuring. Pretreatment of the working electrode was important for the activity and stability of the catalyst layer on the electrode.

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.
