is highly desired to enhance the catalytic activity of oxygen
evolution reaction (OER) electrocatalysts made of earth-abundant elements.
In this Letter, we report that the OER activity of a CuO nanoarray
can be largely enhanced by Co doping. In 1.0 M KOH, the Co-CuO nanoarray
on copper foam requires a current densities of 50 and 100 mA cm–2 at overpotentials of only 299 and 330 mV, respectively.
It also shows superior long-term durability over 15 h with a turnover
frequency of 0.056 mol O2 s–1 at an overpotential
of 300 mV.
