Graphene Derived Materials as Catalysts for the Oxygen Reduction Reaction

Abstract

The conventionally used electrocatalysts for oxygen reduction reaction (ORR) such as PGM and sulphide based, respectively, have contributed negligible or zero-emissions towards global warming. However, there is an urgent need to develop cost-effective, earth-abundant, efficient, non-poisonous and stable electrocatalysts. Through an exhaustive literature survey, it was observed that graphene derived materials are a promising candidate for ORR owing to exceptional electronic, physical and mechanical properties. Furthermore, the surface of graphene derived materials (GDM) can be modified to get desired physicochemical properties and induce electrocatalytic activity by adopting various synthesis methods insynthesis and postsynthesis by insertion of dopants, defect points, surface tuning, making composites, advanced wrapping structures. In the present chapter, fundamental ORR, graphene derived electrocatalysts, and the recent progress of ORR are discussed. © 2022 Bentham Science Publishers.
