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.
