Carbon-based technology has become a multidisciplinary field including
water treatment, agriculture, material science, medicine, and other sciences due to their
unique characteristics. Research on graphene technology has focused heavily on
graphene and its derivatives, including graphene oxide (GO) and reduced graphene
oxide (rGO). Traditional processes for producing rGO involve harsh conditions,
including high temperatures and hazardous chemicals and solvents. The creation of
green-based nanomaterials is the current research focus on a global scale.
Nanotechnological applications are rapidly growing that use agricultural waste biomass
as a reducing agent and turn it into graphene-based products in an effort to lessen their
detrimental effects on the environment. Graphene-based materials and metal
nanoparticles are frequently combined to improve the characteristics of nanomaterials
today with the use of green reductants. Additionally, rGO not only offers the nucleation
site but also prevents metal nanoparticles from clumping together. Here, we discuss the
utilization of agricultural waste biomass for green rGO production and graphene-based
metal nanocomposite, as well as its application to the environment and healthcare.
Finally, this review offers some insight into potential future developments, particularly
with regard to scaling up rGO and graphene-based metal nanocomposites in many
potential applications.
