Polyvinylpyrrolidone (PVP) is a promising material for electrospinning, and it has many desirable properties, including solubility in various solvents, physiological compatibility, chemical inertness, and excellent film-forming ability. PVP nanofiber-webs containing titanium dioxide (TiO2) were prepared via electrospinning. The photocatalytic activities of the electrospun webs were evaluated by analyzing the degradation of methylene blue. The optimum photocatalytic activity was achieved with the webs containing 7 wt% TiO2. The results showed the proposed method to be effective for improving the photocatalytic properties of TiO2-doped nanofibers; the doping process also increased the surface area of the nanofibers. |
