Influence of Defects and Heteroatoms on the Chemical Properties of Supported Graphene Layers

A large and growing number of theoretical papers report the possible role defects heteroatoms on chemical properties single-layer graphene. Indeed, they are expected to modify electronic structure graphene film, allow for chemisorption different species, enable more effective functionalisation. Therefore, from studies, we get suggestion that single double vacancies, Stone–Wales suitable candidates turn nearly chemically inert into an active player in chemistry, catalysis, sensoristics. Despite these encouraging premises, experimental proofs enhanced reactivity defected/doped limited because studies addressing adsorption well-defined layers much less abundant than ones. In this paper, review state art findings heteroatoms, covering topics such as vacancies oxygen carbon monoxide, effect presence N intercalation underneath monolayers, covalent functionalisation defect-induced gas transistors.
