Graphene-quantum-dot-composited platinum nanotube arrays as a dual efficient electrocatalyst for the oxygen reduction reaction and methanol electro-oxidation

Abstract

Well-designed graphene quantum dot composited porous Pt nanotube arrays (GQD–Pt NTAs) are developed as an efficient electrocatalyst for the oxygen reduction reaction (ORR) and methanol oxidation reaction (MOR) in an acidic medium.
