Nov 14, 2016 This work describes a two-step methodology for synthesizing a magnetite nanoparticle-graphene composite. In the first step, iron metal powder was ball milled with graphite to produce a mixture that was subsequently compacted to produce a pellet. In the second step, electrochemical exfoliation of this pellet was performed to produce graphene decorated with magnetite nanoparticles
