Oxygen electrocatalysis is central to technologies such as fuel cells and electrolysers, but challenges remain due to the lack of effective earth-abundant electrocatalysts and insufficient understanding of catalytic mechanisms. Here we demonstrate that robust bifunctional oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) activity can be achieved by inducing lattice strain in noble-metal-free metal–organic frameworks (MOFs). Lattice-strained NiFe MOFs exhibit mass activities of… Expand
