Facile green synthesis of graphene metal nanocomposites and their promising applications

Graphene, a 2D carbon sheet, has attracted tremendous attention in the scientific fraternity. Recently, graphene based metal nanocomposites (GO@Me-NCs) have opened an exciting avenue amongst researchers worldwide, owing to its exceptional properties. Graphene has a high electrical conductivity, exceptional chemical tolerance and large surface-to-volume ratio, which makes it an obvious template for nanocomposites. As a result, incorporation of graphene with inorganic materials such as metal has been the spotlight of research in recent years for their multi-functionalities. From the perspective of chemistry and materials, this account presents an overview of the green and benign processes for fabrication of GO@Me-NCs and their wide range of applications in various fields. Present review highlights the fabrication of GO@Me-NCs by green techniques using plant extracts, carbohydrates, vitamins, amino acids, etc. Finally a concluding remarks are also provided for the researchers, who are interested in designing advanced green strategies for the fabrication of graphene based metal nanocomposites.
