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. [ABSTRACT FROM AUTHOR]
