Abstract
We propose a strategy of phase transformation and electrochemical reconstruction to improve the OER performance of perovskite oxides. The Ru SA -Co 3 O 4 /CoOOH catalyst exhibits an ultra-low overpotential of 175 mV at 10 mA cm −2 , superior to previously reported perovskite-derived OER electrocatalysts.
