Research on Derivatives of Graphene and Their Applications in Catalysis

Abstract

Graphene is a nanomaterial with excellent properties which can be widely used in the field of catalysis. Through functionalization, graphene derivatives can exhibit diverse structures. In this paper, various graphene derivatives have been introduced including halogen-doped graphene, amine of graphene and carboxyl of graphene. In halogen-doped graphene, a successful result on the advancing of the battery are obtained. Amine of graphene has the good sensing applications, and it displays promising use in catalysis process. Carboxyl group of graphene increases its stability at wet condition. The catalytic performance of graphene is closely related to its structure. Therefore, the different catalytic feature of atomic graphene are also discussed in this work. The Pt is used in ORR and the graphene is used to increase its contact area for higher efficiency. Nitrogen-doped graphene strengthens the reactivity of carbon, and the ORR process of it occurs in acidic condition. Phosphorus-doped graphene has dependable electrical catalysis activation, and good ORR stability. Cobalt-doped graphene exhibits good stability and high efficiency in basic ORR condition process. In summary, derivatives of graphene have important application value in catalysis. This work will contribute to the further research of graphene in catalysis.
