Summary:

Carbon nanosheet is a two-dimensional (2D) structure for all the different allotropes of carbon such as carbon nanotubes and graphite. Graphene comprises of less than 10 layers of carbon nanosheet and has extraordinary properties. Graphene has shown promising research results for application in optical electronics, photovoltaic systems, energy storage devices, and many more. The major issue in commercial scale production of graphene lies in its complex manufacturing processes that results in high cost of production. Commonly used production methods (Hummer’s method) use toxic and expensive chemicals and result in generation of hazardous waste. There is a need to develop eco-friendly methods to produce graphene at commercial scale. We have developed an extremely cost effective way of making high surface area graphene from a renewable raw material by using an eco-friendly method. Our green process scales easily and uses agricultural plant as the feedstock. We will present preparation method, and characterization data from Raman spectroscopy, scanning electron microscopy, energy dispersive X-ray spectroscopy, specific surface area analysis, and X-ray diffraction.
