Metal–organic framework derived carbon-confined Ni2P nanocrystals supported on graphene for an efficient oxygen evolution reaction

Metal–organic framework derived carbon-confined Ni2P nanocrystals supported on graphene with high effective surface area, more exposed active sites, and enhanced charge transport were successfully designed. The resulting material shows excellent oxygen evolution reaction performance with a remarkably low overpotential of 285 mV at 10 mA cm−2 and outstanding durability.
