Competing double-exchange and super-exchange interactions yield rich chemistry for understanding robust oxygen evolution activity in Ru-doped lanthanum strontium manganite, with an overpotential of 300 mV at 10 mA cm and a Tafel slope of 110 mV dec. Favourable redox potentials of Mn/Mn and Ru/Ru lead to improved charge transfer kinetics for OER activity.
