Contemporary swing in blending and utilization of graphene based nanocomposites – a review

Abstract

ABSTRACT Many researchers focused on green synthesis of nanomaterials, due to its simplicity, sustainability, environmental-friendly aspect and cost effectiveness. This technique, to a large extent reduce the harmful effects caused by adopting traditional and chemical methods utilized in synthesizing these nanomaterials. A two-dimensional carbon sheet – Graphene has generated huge curiosity in material researchers owed to its unique characteristics suiting varied applications. Graphene, graphene oxide and reduced graphene oxide nano sheets easily can be combined with several metals, metal oxides, nanoparticles of inorganic nature, organic polymers, semiconductors, biomolecules etc. forming a diversity of nanocomposites based on graphene for applications in power, medical therapy, sensing as well as environmental remediation. An analysis prospecting Graphene, reduced graphene oxide and solo layer graphite-based nanocomposites, numerous mechanisms of graphene-based nanocomposites (chemical along with green method), variety of utilization owned by them is presented in this paper. The photocatalytic behaviour of graphene-rooted metal, oxides of metal and oxygen group elements and its composites in nano order prepared through chemical practices and green techniques has been discussed. A remarkable improvement in photocatalytic efficiency has been reported in the composites prepared by green method which can be useful in waste water treatment, industrial and medical applications. This mini review also emphasize that at par with chemically synthesized nanocomposites of Graphene, green synthesized one has highly effective application in antibacterial, cancer therapy, along with sensing utilization.
