Abstract

In this study, Ag doped TiO2 nanofibers were successfully prepared by electrospinning technology for photocatalytic degradation. The structure, morphology and optical properties of the as-prepared nanofibers were analyzed through X-ray diffraction (XRD), field emission scanning electron microscope (FESEM), transmission electron microscope (TEM), and ultraviolet-visible spectroscopy (UV-Vis). Photocatalytic degradation results show that Ag doped TiO2 nanofibers have higher photocatalytic activity than pure TiO2 nanofibers under both visible light and ultraviolet light irradiation, which can effectively improve the degradation efficiency. The best degradation sample in this experiment is 5% Ag doped TiO2 nanofibers, which can complete methylene blue (MB) degradation in 90 minutes under UV light and 70% MB degradation in 240 minutes under visible light.
