Complete Photocatalytic Mineralization of Microplastic on TiO₂ Nanoparticle Film.

ABSTRACT: Recently, the environmental impacts of microplastics have received extensive attention owing to their accumulation in the environment. However, developing efficient technology for the control and purification of microplastics is still a big challenge. Herein, we investigated the photocatalytic degradation of typical microplastics such as polystyrene (PS) microspheres and polyethylene (PE) over TiO₂ nanoparticle films under UV light irradiation. TiO₂ nanoparticle film made with Triton X-100 showed complete mineralization (98.40%) of 400-nm PS in 12 h, while degradation for varying sizes of PS was also studied. PE degradation experiment presented a high photodegradation rate after 36 h. CO₂ was found as the main end product. The degradation mechanism and inte
