In this study, Polyvinylpyrrolidone (PVP) had been chosed as a promising material for electrospun, because it has many desirable properties, such as solubility in various solvents, physiological compatibility, chemical inertness, and excellent film-forming ability. Meanwhile, PVP nanofibers containing titanium dioxide (TiO2) were synthetized via electrospinning. The photocatalytic activities of the samples were investigated by monitoring the degradation of methylene blue with the samples as photocatalyst under irradiation. 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. |
