Photocatalytic Upcycling of Plastic Waste into Syngas by ZnS/Ga2O3 Z‐Scheme Heterojunction

into syngas. Furthermore, this system also demonstrates applicability in the conversion and upcycling of other polyolefin plastics including polypropylene and polyvinyl chloride. Our findings highlight the potential of polyolefin plastics photoreforming for the production of syngas under environmentally benign conditions.
