The effect of ball milling and the addition of carbon on the physico-chemical properties as well as the OER performance of the Ba0.5Sr0.5Co0.8Fe0.2O3 (BSCF) perovskite is investigated. We show that the ball milling process can significantly enhance the BSCF OER activity. This higher activity is asso...
