ClearComprehensive Insights into Photoreforming of Waste Plastics for Hydrogen Production
This review examines photocatalytic "photoreforming" — a solar-powered process that breaks down waste plastics while simultaneously generating hydrogen fuel and useful chemical byproducts. Recent advances in catalyst design, including semiconductor materials and metal-organic frameworks, are analyzed alongside factors like light intensity and pH that affect hydrogen output. This dual-purpose approach could help address both the global plastic waste crisis and the need for clean energy simultaneously.
