A facile method to prepare hybrid cellulose acetate nanofibers containing TiO (TiO-CA nanofibers) by emulsion electrospinning technique was developed for the denitrification and filtration of particulate matters (PMs). This work found that hybrid TiO-CA nanofibers mainly contain the anatase form of TiO, contributing to the photodecomposition of NO gas under UV irradiation. The TiO-CA nanofibers also showed an excellent filtration efficiency of 99.5% for PM and a photocatalytic efficiency of 78.6% for NO removal. Furthermore, the results implied that the morphology of the TiO-CA nanofibers, such as micro-wrinkles and protrusions, increased the surface hydrophobicity up to 140°, with the increased addition of TiO nanoparticles. The proposed TiO-CA nanofibers, as a result, would be promising materials for highly efficient and sustainable air filters for industrial and home appliance systems.
通过乳液静电纺丝技术制备含TiO的混合醋酸纤维素纳米纤维（TiO-CA纳米纤维）的简便方法被开发用于反硝化和颗粒物（PMs）过滤。这项工作发现，混合TiO-CA纳米纤维主要包含锐钛矿形式的TiO，有助于在紫外光照射下对NO气体进行光分解。TiO-CA纳米纤维对PM的过滤效率也高达99.5%，对NO去除的光催化效率为78.6%。此外，结果表明，随着TiO纳米颗粒添加量的增加，TiO-CA纳米纤维的形态，如微皱纹和突起，使表面疏水性增加到140°。因此，所提出的TiO-CA纳米纤维将是用于工业和家电系统高效且可持续空气过滤器的有前景的材料。
