In this research, tungsten doped titanium dioxide nanofibers were prepared by the hydrothermal method and used as a photocatalyst in the photocatalytic process. The prepared samples were investigated by XRD, FESEM, and UV-vis spectrophotometer. The experimental results show that the prepared samples have an anatase phase and absorb UV light. In addition, it was found that the increased amount of tungsten resulted in larger crystal size. For the efficiency of paraquat degradation by the photocatalytic activity of the prepared nanofibers, it was found that the W:15TiO 2 nanofibers had the highest efficiency of paraquat degradation. It can degrade 73.97% of paraquat in 120 min.
