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