title: Green synthesis of graphene.
abstract: The present work reports a green route to synthesis of graphene by reduction of graphite oxide with cocos nucifera L. (coconut water) as reducing agent which is naturally available, non-toxic and environmental friendly. The graphite oxide has been prepared by oxidation of graphite with KCIO3/NaNO3/H2SO4 as reported in our earlier findings. X-ray diffraction, FTIR, UV-Visible and Raman spectroscopy confirmed the formation of graphene. SEM, TEM and AFM analyses have also been carried out to study the morphological characteristics of the obtained product. Also, TG analysis presents the thermal stability behavior of the formed product. Zeta potential measurements were also carried out to determine the surface charge characteristics.
