Layered Ruddlesden-Popper La2NiO4+δ (LNO) is reported to possess excellent oxygen surface and bulk transport properties, but its application as the cathode of solid oxide fuel cells is restrained by the relatively poor electrocatalytic activity. Here, we report the incorporation of highly ion-conduc...
