Dealloyed RuNiOx as a robust electrocatalyst for the oxygen evolution reaction in acidic media

We report here the dealloying treatment on a RuNiOx catalyst for enhanced acidic oxygen evolution reaction (OER) performance. Specifically, the dealloyed RuNiOx is capable of delivering a current density of 50 mA cm-2 at a low overpotential of 280 mV and demonstrates superior stability after 10 000 potential cycles.
