“…1,24 3D graphene sponges can be used as potential adsorbents due to their remarkable uniform pore size Environmental Science: Nano Tutorial review and high adsorption performance, which were generally synthesized using a hard template method. 25,26 Recently, graphene with different morphologies was obtained using different carbon resources such as coal, biochar, carbon black, discarded food and mixed plastic wastes. 29 Luong et al synthesized the gram-scale yield (80-90%) of highly pure graphene (99%) by using the flash Joule heating (FJH) of a carbon source, such as high-carbon source, discarded food, rubber tires and mixed plastic waste.…”
