Co-MOF catalyzes the ORR efficiently with a lower onset potential (0.85 V vs. 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.

A single step redox approach that transformed the crystalline Ni-MOF to amorphous nickel boride (NiB) nanostructures showed excellent electrocatalytic (oxygen evolution reaction; OER) and charge storage (supercapacitor) performances.

The oxygen evolution reaction is a kinetically sluggish half-cell reaction plays an important role in tuning the efficiency of various electrochemical energy conversion systems. However, this process can be facilitated...
