•A short assessment of the established chemical methods for reduction of graphene oxide was carried out along with their adverse effects.•Detail study of green methods for reduction of graphene oxide using microbial degradation was carried out.•In-depth review of graphene oxide reduction using plant extract was conducted.•Methods that employed biomolecules for the reduction of graphene oxide were studied in detail.•Roles of green technology in current and future research on reduction of graphene oxide were also appraised.
Graphene has occupied the central stage in material science research all over the world. Various techniques and methods have emerged, the most common being top down approach, where graphene is synthesized from graphite. In this approach, reduction of graphene oxide is considered as the most important step and it is generally achieved by strong chemical reducing agents such as NaBH4 and hydrazine hydrate. But now, new generation of researchers have developed various natural and eco-friendly methods of reducing graphene oxide. This review summarizes the green methods employed in natural reduction of graphene oxide, which includes use of biomolecules, microorganisms and plant extracts. Issues and challenges are raised to provide pathways for future endeavors that will translate into service delivery for the benefit of human.
