Construction of bimetallic phosphide nanostructures with in situ growth, reduction, and phosphidation of ultra-thin graphene layers as highly efficient catalysts towards the OER

In-situ growth of bimetallic silicate onto ultrathin graphene, followed by reduction and phosphorization to obtain uniformly dispersed Fe x NiP on graphene layers. rGO@Fe0.8NiP exhibits excellent OER activity and the overpotential ( η 10 ) is 266 mV.
