Kanpur: National Sugar Institute, Kanpur, got a patent for developing an innovative technique for ‘Production of Graphene Oxide from sugarcane bagasse’. The technique has been developed by Vishnu Prabhakar Srivastava, assistant professor of organic chemistry under the guidance of Prof Narendra Mohan, director, National Sugar Institute.
“We are continuously working on developing newer techniques for production of bio-chemicals and bio-energy from the by-products of the sugar industry, and “Graphene Oxide” is one such product which we have developed after several years of research work”, said Prof Narendra Mohan.
The process involved catalytic carbonization-cum-graphitization, subsequent treatments with acid and other solvents, followed by oxidation. Graphene oxide can be used for production of graphene. Currently, graphene production is a very high cost affair and it is mostly prepared from graphite.
The current market price of “Graphene Oxide” is Rs. 85-300 per gram depending upon its purity. Due to extraordinary properties, graphene and graphene oxide can be applied in many applications. Graphene Oxide is used for fabricating sensors and bio-sensors, storage of high capacity energy, in solar panels, production of anti-cancer drugs and for fabricating flexible displays.
“Considering the cost and availability of raw material that is bagasse and technology developed for its conversion to “Graphene Oxide”, it will be possible to produce it at a lower cost”, said assistant professor Vishnu Prabhakar Srivastava.The above news was originally posted on timesofindia.indiatimes.com
