英文摘要 | The TiO₂ was immobilized onto the polymer fibers as composite nonwoven fiber textile by using silica sol. The photocatalytic efficiency of nonwoven fiber textile was tested on degradation of gaseous 2-propanol in a batch photoreactor for three months. From the durability tests of nonwoven fiber textiles, it was confirmed that composite nonwoven fiber textile had high TiO₂ immobilization ability and the photocatalytic efficiency was found to be dependent on the amount of silica sol addition. After three month usage, the photoactivity of 0.5 wt% SiO₂ addition nonwoven fiber textile presented higher photocatalytic efficiency than that of TiO₂ textile, which had poor photocatalytic efficiency due to the reduction of the retained TiO₂ amount. The effects of silica sol additives on material characteristics and photocatalytic activities of nonwoven fiber textiles are discussed. |
