Abstract

Magnesium doped ultra-fine RuO₂ nanoparticles are prepared by a one-step annealing of Ru-exchanged Mg-MOF-74. Mg–RuO₂ exhibits excellent oxygen evolution reaction performance with a low overpotential of 228 mV at 10 mA cm⁻². The excellent performance is attributed to the altered electronic structure and the optimized surface atomic arrangement.
