하이브리드 이산화티타늄-셀룰로오즈 아세테이트 나노섬유의 광촉매 효과와 미세먼지 여과효과 |
| 초록 |
A facile method to prepare hybrid cellulose acetate nanofibers containing TiO2 (TiO2 -CA nanofiber) by emulsion electrospinning technique was developed for denitrification and the filtration of particulate matters (PMs). This work found that hybrid TiO2-CA nanofibers contain mainly anatase form of TiO2 which attributed photodecomposition of NO gas under UV irradiation. TiO2-CA nanofibers also showed excellent filtration efficiency of 99.5% for PM0.5 and the photocatalytic efficiency of 78.6% for NO removal. Furthermore, the results implied the morphology of TiO2-CA nanofibers such as micro-wrinkles and protrusions increased the surface hydrophobicity up to 140° with increased addition of TiO2 nanoparticles which closely related to photocatalytic efficiency. The proposed TiO2-CA nanofibers would be promising materials for use as highly efficient and sustainable air filters for industrial and home appliance systems. |
