In this study, PAN/TiO2 fiber mats were fabricated from polyacrylonitrile (PAN) and titanium(IV) butoxide (Ti(OBu)4) by an electrospinning method with various solution concentrations, applied voltages and solution flow rates. The fiber mats were irradiated with an electron beam to induce structural crosslinking and enhance photocatalytic activity. As a result, uniform and bead-free fibers without pits or cracks on surface were obtained at 5 wt% of Ti(OBu)4 solution with 15 kV and 0.02 mL/min flow rate. The PAN/TiO2 fiber mats were irradiated with an electron beam of 1.14 MeV acceleration voltage, 4 mA of current and 1 × 104 kGy. Electron beam irradiation was enhanced the photocatalytic activity of PAN/TiO2 nano fiber mat. The photocatalytic activity of the PAN/TiO2 fiber mat was analyzed by degradation of methylene blue and volatile organic compounds.
