  • Method of preparation of reduced graphene oxide(rGO)
    Patent number: 11897772
    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.
    Type: Grant
    Filed: May 22, 2019
    Date of Patent: February 13, 2024
    Assignees: TATA STEEL LIMITED, CENTRE FOR NANO AND SOFT MATTER SCIENCES
    Inventors: Anand Sen, Sumitesh Das, Shyam Kumar Choudhary, Giridhar Udapi Rao Kulkarni, Murali Gedda, Rajashekhar Ningappa Pujar
