CuxCo3−xO4 (0 ≤x < 1) nanoparticles for oxygen evolution in high performance alkaline exchange membrane water electrolysers
Abstract
Cu incorporated Co3O4 (CuxCo3−xO4, 0 ≤ x < 1) nanoparticles were prepared using a thermal decomposition method. Properties of the CuxCo3−xO4, such as morphology, particle sizes, crystallite structure and cation distribution, were characterized with SEM, TEM, XRD and EDX. The CuxCo3−xO4 particles, with various x values, were found to be cubic spinel nanoparticles, with average size of 20–30 nm. Incorporation of Cu in the spinel lattice of Co3O4 shifted the Co3+/Co4+ redox peak as well as the onset point for OER to more negative potentials, which may be related to inversion of Cu2+ into the octahedral sites. Amongst all samples studied, Cu0.7Co2.3O4 was the most active for OER. The CuxCo3−xO4 electrodes exhibited satisfying stability during repetitive cyclic voltammetry. A membrane electrode assembly, using 3 mg cm−2 Cu0.7Co2.3O4 on the anode, demonstrated, in an alkaline membrane water electrolyser, a high current density performance of 1 A cm−2 at a voltage of 1.8 V in 1 mol dm−3 KOH at 25 °C.

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.
