Scientists at the Institute of Nano Science and Technology (INST) in Mohali, Punjab, have devised a scalable and sustainable solution that produces high-quality graphene nanosheets using waste peanut shells. The shells are “carbonised” and processed to form small, low volume pores that increase the surface area available for chemical reactions. This then undergoes “mechanical exfoliation”, a process that uses sound waves to agitate the material into forming a stable structure akin to graphene. After suitable tests were carried out, researchers found that they had produced high-quality graphene nanosheets.
