Photocatalytic Degradation of Microplastic in the Environment
AI summary Read the abstract
Researchers reviewed photocatalytic degradation as a promising approach for breaking down microplastics in the environment, finding it may offer advantages over incineration and filtration — though practical challenges around scale and efficiency remain.
Microplastic pollution is reported as an emerging environmental pollutant that needs a promising solution because of its uncontrolled occurrence, distribution, non-visibility, and long lifetime. Different methods were tested such as incineration, filtration,...

Photocatalytic-Driven Self-Degradation of Polyester Microplastics Under Solar Light
AI summary Read the abstract
"Researchers synthesized a polyester fiber modified with a g-C3N4/TiO2 photocatalyst that can self-degrade under solar illumination, achieving near-complete breakdown into CO2 and water after 400 hours of light exposure. Designing plastics that decompose under sunlight rather than fragmenting into persistent microplastics offers a proactive materials-level strategy to reduce the volume of synthetic polymer pollution entering ecosystems."
Evaluation of Microplastic Degradation Using Titanium Dioxide Photocatalyst in Water
AI summary Read the abstract
Researchers tested UV light and titanium dioxide photocatalysis to break down microplastic fibers in water, achieving a 97% reduction in mass within 48 hours under optimized conditions, suggesting this approach could be a viable treatment technology for wastewater facilities.
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.
