“…The morphology of the prepared TiO 2 films was characterized by using field-emission scanning electron microscopy (FE-SEM) (Figures 4C-4E). Figure 4E revealed that the presence of Triton X-100 significantly affected the morphology of TiO 2 (Suwanchawalit et al, 2017), such as the formation of nanoparticles, induced a particle size reduction, and fine pore formation (Godinez and Darnault, 2011). Particle size can influence the surface area and the recombination rate of photogenerated electron-hole pairs.…”

Summary 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 TiO 2 nanoparticle films under UV light irradiation. TiO 2 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. CO 2 was found as the main end product. The degradation mechanism and intermediates were studied by in situ DRIFTS and HPPI-TOFMS, showing the generation of hydroxyl, carbonyl, and carbon-hydrogen groups during the photodegradation of PS. This study provides a green and cost-efficient strategy for the control of microplastics contamination in the environment.
