제목 Photocatalytic performance with color change controlling VOCs in the air
초록 When photocatalysts get light energy and act as a catalyst, affecting reaction rates in chemical reactions. As light is emitted, it behaves like electrons (e-) and holes (electrons with positive charges) on the surface, and electrons react with oxygen and water around the photocatalyst, resulting in hydroxyl radical (neutral OH). 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 (white) and merocyanine (pink) by performance of photocatalysts.
