From: Mechanistic insights of enhanced spin polaron conduction in CuO through atomic doping
J−V plots (scan rate = 10 mV/s) of CuO (black) and Li-doped CuO (red) electrodes for O2 reduction in 0.1 M KOH (pH 13) solution with O2 purging under AM1.5G,100 mW/cm2 illumination. The inset shows the enlarged current in the potential region near the photocurrent onset potentials indicated by arrows
