Abstract: In this article, we have isolated Graphene nanosheets from Graphite rod using sandpaper at room temperature without involving the usage of any chemicals, reagents or thermal energy. The isolated Graphene nanosheets were characterized by TEM, XRD and Raman spectroscopy. It was further used as a photocatalyst in the degradation of Malachite Green. The entire photocatalytic dissociation of the dye was carried under ambient room temperature (~ 27ᵒ C) and commercial CFL lamp (visible light induced). The absorbance of the dye was analyzed by UV – Vis spectrophotometer at an interval of 15 minutes over an hour. The photocatalytic-kinetics of the dye dissociation was calculated and plausible mechanism of the Graphene as photocatalyst was proposed.
