In this study, the creation of hybrid TiO2 with spiropyran was considered to control VOCs in the air to cause fine/ultrafine particle (PM 2.5) pollutants. TiO2-spiropyran polyemrs were synthesized and then grafted to electrospun nanofibers. Such functional nanofibers can change chromatic properties according to the switching colors between spiropyran by performance of photocatalysts. Developed light responsive hybrid TiO2-spiropyran photocatalysts that dynamically changed leading to the formation of smart surfaces and open access to promising various applications for smart textiles, biosensors, and photocatalytic composites. In order to evaluate NO removal properties, the model is developed and evaluated efficiency of photocatalyst by colorimetric analysis. This evaluation work contributes to the development of hybrid TiO2 with color sensor and provides high performance in detecting and controlling NO and PM 2.5 contaminants, which can cause lungs and threaten human life. |
