Polyvinylpyrrolidone(PVP) nanofibers loaded on kryptol were fabricated from PVP sol via an electrospinning technique,followed by preoxidation at 250℃ and carbonization at 850℃.To obtain TiO₂ nanoparticles loaded on these carbon nanofibers,the carbon nanofibers were firstly soaked by titanium n-butyloxide(Ti (OC₄ H_9n)₄) and subsequently heat-treated at 200℃ and calcined at 550℃.The morphologies and structure of the products were investigated by scanning electron microscopy(SEM),Fourier transform infrared spectrometry(FT-IR),and X-ray diffraction(XRD). TiO₂ loaded on carbon nanofibers were used to study the degradation of methylene blue(100 mL 2.0 mg/L methylene blue) under UV irradiation for 40 min. The obtained nanocomposite exhibited a higher photo-catalytic activity and the degradation percentage of methylene blue was higher than 75%.
