Researchers from Australia’s University of New South Wales (UNSW), Australian Nuclear Science and Technology Organization (ANSTO) and The Hong Kong Polytechnic University have developed a rapid, highly efficient process to synthesize graphene from discarded peanut shells – turning what agricultural waste into a high-value nanomaterial.
The team, led by Professor Guan Yeoh from UNSW’s School of Mechanical and Manufacturing Engineering, used a two-stage heating strategy that dramatically improves the energy efficiency and quality of the resulting graphene compared to traditional high-temperature or chemical routes. Their work shows how precursor engineering – the controlled pre-treatment of raw biomass – determines the structural order and electronic quality of the resulting graphene.
