    Facile Electrochemical Synthesis of Highly Efficient Copper-Cobalt Oxide Nanostructures for Oxygen Evolution Reactions by Nath, Narayan Chandra Deb

    Published 2020
    “…An optimized nanopetal structure of CuxCo3-xO4 (x = 0.95, annealed at 200 °C) shows a considerably high Faradaic efficiency (∼93%) with a remarkably low overpotential (∼230 mV) at a benchmark current density (J) of 10 mA cm-2; at the same J in an alkaline solution (1 M KOH) for OER, it also exhibits high durability (up to 100 h). …”
