A cobalt metal–organic framework (Co-MOF): a bi-functional electro active material for the oxygen evolution and reduction reaction

Co-MOF catalyzes the ORR efficiently with a lower onset potential (0.85 Vvs.RHE) by a four electron reduction path with better durability. It needs only 280 mV overpotential to deliver the state-of-art current density of 10 mA cm⁻².
