Electrospinning CeO2/g-C3N4 Nanofibers for Efficient Photocatalytic Degradation Performance

A serials of nanofibers with different contents of CeO2 were successfully fabricated by electrospinning techniques. The structure, morphology and optical properties were characterized by X-ray diffraction, Scanning electron microscopy, Fourier transform infrared spectra, X-ray photoelectron spectroscopy, UV-Vis spectroscopy. The catalytic properties of CeO2/g-C3N4 composites were evaluated using tetracycline hydrochloride under simulated solar light illumination. When the loading amount of CeO2 was 5.0 wt %, the composite showed the highest catalytic activity, which was 5.8 times that of porous g-C3N4. The enhanced photocatalytic properties of CeO2/g-C3N4 may be attributed to effective separation of photogenerated carriers and enhanced absorption of visible light. The photocatalyst had an excellent catalytic stability and possible photodegradation mechanism of the obtained sample was proposed.
