(a) UV-vis spectra and (b) PL spectra of TiO2, TZ-5, TZ-10, TZ-20, and P25. (c) Photocatalytic degradation performance and (d) kinetic linear fitting curves of MB over different samples under UV light irradiation. The inset showing the corresponding Kubelka-Munk transformed reflectance spectra to determine the indirect new bandgap values of the as-synthesized nanofibers.
