Abstract
The present disclosure provides a simple and inexpensive method to produce reduced Graphene oxide (rGO). The method comprises conversion of low-cost carbon sources such as coal tar pitch (industrial by-product) into a high quality rGO wherein said conversion is carried out by annealing the carbon source at two different temperatures. The rGO is obtained at high yields by employing the present method and the obtained rGO demonstrates high conductivity and good surface area along with very low oxygen content.
