Abstract:The selective upgrading of polyethylene waste into light aromatics is hampered by relatively high C−C bond cleavage temperatures and low product selectivity. Herein, we report a lowtemperature melting-catalysis strategy that directly upgrades lowdensity polyethylene (LDPE) into light aromatics over commercial ZSM-5 zeolite under mild conditions, eliminating the need for precious metals, solvent, or external H 2 . Experimental results combined with DFT calculations and molecular dynamics simulations revealed th… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
