Summary

This review assessed titanium dioxide (TiO2) photocatalysis as a method for degrading macro- and microplastics, finding that UV-activated TiO2 can break polymer chains through reactive oxygen species under controlled conditions. Scalable photocatalytic degradation is a compelling remediation strategy because it can destroy microplastics rather than relocate them, potentially reducing the volume of particles available for human ingestion and environmental accumulation.

The growing environmental threat posed by macro- and microplastics has intensified the search for sustainable degradation methods. Photocatalysis, using titanium dioxide (TiO₂) as a catalyst, has emerged as an efficient and eco-friendly approach to breaking...
