Abstract
Graphene in the form of film, fiber, fabrics and composites is widely investigated research area because of its remarkable physical, chemical and thermal properties. The acceptance of plant-derived products to synthesize graphene or reduced graphene oxide (RGO) has the supremacy of environmentally friendly, mild reaction condition, sustainability, cost effective and simple reaction procedure compared with conventional chemical synthesis methods. To synthesize RGO from graphene oxide (GO) in traditional chemical reduction method, highly toxic and hazardous reducing agents, capping agents, solvents are generally employed which severely affect and threaten ecological equilibrium and human well-being. In this paper, different highly facile and eco-friendly, low-cost green synthesis of RGO using aqueous plant extracts have been surveyed. The phytochemical present in plant extract, methods of preparation of the extract, detection of phytochemical present in extract, preparation of GO, methods of reduction of GO, mechanism of reduction of GO by greener way are discussed.
