Low-emissions strategy that could pay for itself helps scientists achieve high-yield hydrogen gas and high-value graphene.
Kevin Wyss, a Rice University’s doctoral alumnus and lead author of the study, said that the team converted waste plastics – including mixed waste plastics that don’t have to be sorted by type or washed – into high-yield hydrogen gas and high-value graphene.
Green hydrogen, derived from renewable energy sources, which experiences a process of water splitting into two components, is priced at approximately $5 for slightly more than two pounds. The scientific process of creating hydrogen from plastic waste material involves exposing the waste samples to rapidfor nearly four seconds. This brought the temperature up to 3100 degrees Kelvin.
“We wondered what they were, suspecting a mix of small hydrocarbons and hydrogen, but lacked the instrumentation to study their exact composition.”
