Nanotechnology-Enhanced Photocatalysis for Microplastic Degradation: A Sustainable Approach

Photocatalytic Degradation of Macro—and Microplastics Using Titanium Dioxide (TiO₂)

AI summary · Read the abstract

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.
