Abstract
A facile method to prepare hybrid cellulose acetate nanofibers containing TiO(2) (TiO(2)-CA nanofibers) by emulsion electrospinning technique was developed for the denitrification and filtration of particulate matters (PMs). This work found that hybrid TiO(2)-CA nanofibers mainly contain the anatase form of TiO(2), contributing to the photodecomposition of NO gas under UV irradiation. The TiO(2)-CA nanofibers also showed an excellent filtration efficiency of 99.5% for PM(0.5) and a photocatalytic efficiency of 78.6% for NO removal. Furthermore, the results implied that the morphology of the TiO(2)-CA nanofibers, such as micro-wrinkles and protrusions, increased the surface hydrophobicity up to 140°, with the increased addition of TiO(2) nanoparticles. The proposed TiO(2)-CA nanofibers, as a result, would be promising materials for highly efficient and sustainable air filters for industrial and home appliance systems.
