Electrocatalysts Based on Graphene and Its Composites

Abstract

Graphene, a two-dimensional carbon material, has managed to attract the attention of the scientific world since its discovery because of its extraordinary properties. The number of studies on the development of graphene-based materials has increased with the achievement of significant success in different studies investigating the applicability of graphene. In particular, the preparation of graphene and its derivatives with simpler methods—and the addition of different components to its structure, thereby obtaining graphene-based composite materials—provides great advantages for many applications. Developed graphene-based composites are used as electrochemical catalysts in different application areas. The aim of this chapter is to explain the types of graphene-based composites after introducing the properties and synthesis methods of graphene and graphene-based composites. Then, the studies on graphene and graphene-based composites, which are widely used as electrocatalysts, are briefly reviewed.
