采用静电纺丝技术和层层组装技术制备了聚电解质/TiO2复合中空纳米纤维膜。通过控制PS纤维模板直径和吸附层数,TiO2中空纤维的直径和壁厚得到了很好的控制。在光催化降解乙醛性能实验中,TiO2中空纤维具有比P25更好的光催化性能。
Hybrid multilayered hollow nanofibers composed by TiO2/ potyelectrolyte (PE) nave been prepared by a combination of electrospinning method and layer-by-layer (LBL) technology. The results show that the average diameter of the hollow nanofibers and the wall thickness can be well controlled by the template as well as the numbers of the coating layers. When comparing with other nanostructured TiO2 materials such as commercial TiO2 nanoparticles (P25, Degussa) and TiO2 films, the hollow TiO2/PE hybrid nanofibers exhibited higher photocatalytic activities.
