Abstract

Recently, graphene-based materials have attracted significant attention from scientific and industrial communities due to their potential applications in various electrochemical energy conversion technologies. Since pure graphene is electrochemically inert despite its outstanding versatile properties, different strategies are employed to modify the graphene to enhance its electrochemical activity. In this chapter, first, we discuss the basics of electrocatalysis and then the recent advances in electrocatalysis by graphene-based materials. Electrocatalytic activities of non-metal doped graphene, graphene-based 2D heterostructures, and graphene-plasmonic nanostructures have drawn particular attention. The challenges and future prospects of graphene-based electrocatalysts are also highlighted.
