Abstract

We report here the dealloying treatment on a RuNiO_x catalyst for enhanced acidic oxygen evolution reaction (OER) performance. Specifically, the dealloyed RuNiO_x 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.
