Jolts of electricity can convert discarded plastic into hydrogen gas and graphene, potentially offering a way to manage a growing waste problem while also producing an environmentally-friendly fuel (Adv. Mater. 2023, DOI: 10.1002/adma.202306763). The team behind the work, led by James M. Tour at Rice University, calculates that the commercial value of the graphene should more than offset the costs of the process, essentially offering a free source of hydrogen gas.
