Suppressing Hydrogen Transfer and Aromatization Reactions Enables Efficient Photothermal Recycling of Polyethylene into Platform Olefins

olefins, in the photothermal recycling of low-density PE (LDPE) under atmospheric pressure using Xe lamp irradiation. Further, the demonstrated universality across various PE feedstocks (e.g., high-density PE and commercial LDPE bags) and concentrated sunlight operation highlights a solar-powered plastic-to-olefin platform with industrial viability.
