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 -2 and a Tafel slope of 110 mV dec -1 . Favourable redox potentials of Mn 3+ /Mn 4+ and Ru 4+ /Ru 5+ lead to improved charge transfer kinetics for OER activity.
