Photocatalytic Technologies for Transformation and Degradation of Microplastics in the Environment: Current Achievements and Future Prospects
Summary
This review examines photocatalytic technologies that use light-activated materials to break down microplastics in the environment. Various catalysts can generate reactive oxygen species that degrade plastic polymers into simpler, less harmful molecules. The authors assess the strengths and limitations of different photocatalytic approaches and highlight the need for scalable solutions that work under real-world environmental conditions.
Microplastic (MP) pollution has emerged as a significant environmental concern, with exposure to it linked to numerous negative consequences for both ecosystems and humans. To tackle this complex issue, innovative technologies that are capable of effectively eliminating MPs from the environment are necessary. In this review, we examined a variety of bare and composite photocatalysts employed in the degradation process. An in-depth assessment of the benefits and drawbacks of each catalyst was presented. Additionally, we explored the photocatalytic mechanisms and factors influencing degradation. The review concludes by addressing the current challenges and outlining future research priorities, which will help guide efforts to mitigate MP contamination.
