Figure 3
(a) Ohmic resistance-compensated polarization curves of the oxygen evolution reaction (OER) for Ni2P/C, and (b) overpotentials (η) at 10 mA cm−2 of Ni2P/C and NiO/C with respect to the potential cycles. All measurements were performed in 0.1 M KOH saturated by high purity oxygen (99.999%) at room temperature.
