Abstract

Abstract:

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(OC4H9n)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%.

Key words: electrospinning, carbon nanofibers, titanium dioxide, photodegradation of methylene blue
