Highly effective photocatalytic degradation of plastic film (LDPE) using Ruthenium-incorporated g-C3N4 via the Norrish mechanism

Research progress on photocatalytic degradation of microplastics by graphitic carbon nitride

AI summary · Read the abstract

This review systematically examined graphitic carbon nitride (g-C3N4) as a photocatalytic tool for degrading microplastics, identifying hydroxyl radicals, holes, and superoxide radicals as the key reactive species and showing that pH, light intensity, and MP morphology significantly affect degradation efficiency. While still at laboratory scale, photocatalytic degradation offers a chemical pathway to break down persistent microplastics in water—an important complement to physical filtration approaches.

Advanced photocatalytic materials for micro/nanoplastic degradation: A comprehensive review

AI summary · Read the abstract

Tiny plastic particles called micro- and nanoplastics are turning up everywhere, in our oceans, soil, and likely our bodies, raising concerns about long-term health effects. This review rounds up the latest science on using light-activated materials (photocatalysts) to break down these plastic particles, including newer "green" methods made from plants, algae, and bacteria that could make cleanup cheaper and more eco-friendly. While these technologies are still being developed rather than ready for widespread use, they represent a promising direction for tackling plastic pollution at its source.

Photocatalytic degradation of polyethylene terephthalate nano and microplastics over ilmenite-graphene oxide nanohybrid

AI summary · Read the abstract

Researchers combined natural ilmenite mineral with graphene oxide to create a photocatalyst that degraded 100% of PET plastic particles in water under UV light, outperforming previous methods. This eco-friendly approach offers a promising tool for removing nanoplastics and microplastics from drinking water without generating harmful byproducts.
