Three dimensional nanocomposite of reduced graphene oxide and hexagonal boron nitride as an efficient metal-free catalyst for oxygen electroreduction

Abstract

Excellent ORR kinetics by an h-BN/rGO nanocomposite is shown with an onset potential ∼0.8 V<italic>vs.</italic>RHE, attributed to the segregation mechanism and coalescence of graphitic planes of h-BN and rGO.
