A study focused on turning waste plastics into high-value graphene just unlocked a new way of producing hydrogen that could transform the nascent industry and, on a grander scale, positively alter projected decarbonization pathways. The breakthrough could be a win-win for the environment, recycling plastic waste – of which the world has approximately 6.3 billion tons – while providing high-yield hydrogen gas which can be used as clean fuel, all while producing graphene as an end product which makes the whole process economically viable. The breakthrough is detailed in a new paper in Advanced Materials.
