Abstract The traditional electrospinning method is usually used to prepare solid and smooth surface single-component nanofibers by a single capillary nozzle, which restricts its application in preparation of composite with multiple functional structures. In this work, TiO₂/g-C₃N₄ composite were successfully synthesized by coaxial electrospinning using butyl phthalate and urea as the raw material. The samples were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), ultraviolet visible diffuse reflectance spectroscopy (UV-vis DRS), scanning electron microscopy (SEM) and Brunauer Emmett Teller (BET) analysis, etc. The effect of g-C₃N₄ addition on the photocatalytic performance of TiO₂/g-C₃N₄ composite was studied by photocatalytic degradation using methylene blue (MB) as the objective. The results show that TiO₂/g-C₃N₄ composite with larger surface area and high photocatalytic performance were successfully prepared by coaxial electrospinning coupled with calcination at 500℃. When the content of g-C₃N₄ was 0.15 g, the photocatalytic degradation efficiency of methylene blue (MB) by TiO₂/g-C₃N₄ composite material reached 93.8%, and the degradation rate can still reach more than 80% after 5 repeated experiments.
