Abstract

In this work, we report a straightforward in situ leaching strategy to achieve rapid structure self-reconstruction of NiRu-OH/NF. The as-prepared electrode shows excellent OER performance with a low overpotential of 321 mV at 100 mA cm^-2. It can deliver 10 mA cm^-2 at 1.53 V in a water-alkali electrolyzer as the anode and operates steadily at 100 mA cm^-2 with a small cell voltage for 50 h.
