Solid- and aqueous-phase approaches on zinc oxide-based photocatalytic system for degradation of plastics and microplastics: A review

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.
