Efficient tri-metallic oxides NiCo₂O₄/CuO for the oxygen evolution reaction.

ABSTRACT: In this study, a simple approach was used to produce nonprecious, earth abundant, stable and environmentally friendly NiCo₂O₄/CuO composites for the oxygen evolution reaction (OER) in alkaline media. The nanocomposites were prepared by a low temperature aqueous chemical growth method. The morphology of the nanostructures was changed from nanowires to porous structures with the addition of CuO. The NiCo₂O₄/CuO composite was loaded onto a glassy carbon electrode by the drop casting method. The addition of CuO into NiCo₂O₄ led to reduction in the onset potential of the OER. Among the composites, 0.5 grams of CuO anchored with NiCo₂O₄ (sample 2) demonstrated a low onset potential of 1.46 V vs. a reve
