Graphene based non-noble metal catalyst for oxygen reduction reaction

Abstract

Abstract The current noble-metal Pt based oxygen reduction reaction electrocatalysts suffer from high cost and poor operational durability. It is an urgent demand to developing alternative catalysts that are cost effective, readily available, and have the comparable catalytic activity than Pt for oxygen reduction reaction. Recently, graphene-based non-noble metal catalysts have been investigated and shown desirable activity and stability toward oxygen reduction reaction. Here, we offer a timely review paper to illustrate the recent progresses of graphene based electrocatalyst, including heteroatom doped graphene and graphene-inorganic nanoparticle composite. We hope this article can provide a guideline for rational design of highly active graphene-based non-noble metal catalysts toward oxygen reduction reaction.
