Abstract
Abstract Nanofiber based materials are common media for wastewater treatment but often limited with the efficiency and cost-effective in practical application. In this work, TiO2 nanoparticles were evenly immobilized in the poly (vinyl alcohol-co-ethylene) nanofibrous scaffold by a novel facile method based on the melt phase separation technique. Methylene blue (MB) was chosen as a model pollutant to evaluate the synergistic effect on the hybrid film. The experimental results showed that the hybrid film with embedded TiO2 nanoparticles exhibits highly removal efficiency of MB under UV irradiation, reaching to 97.3% within 150 min, and could be further enhanced by coupling with a dye-enriched filtration process. Meanwhile, this excellent photocatalytic activity allow the hybrid film to be regenerated rapidly and repeated used with no significant decrease in its filtration performance. Thus, this promising filtration capability, highly photocatalytic degradation activity and well repetitive use performance would make the hybrid film as an ideal candidate to effective removal of organic dyes from wastewater.
