Two-dimensional materials are currently in the forefront of material research. The graphene and other 2D materials play key role in electrocatalysis as well as energy storage and related field. In this presentation will be discussed the influence of impurities present in graphene and other 2D nanomaterials nanomaterials on electrocatalysis. The synthesis procedures typically introduce various impurities of metallic and non-metallic ions. Their presence can dominate electrocatalytic properties like for hydrogen evolution reaction and oxygen reduction reaction. The other factor influencing electrocatalytic activity like structure, particle size and edge vs basal planes of two-dimensional materials will be discussed. The experiments using single crystal electrodes shows dominant effect of edges for the electrocatalytic properties.
