Electrospinning CeO 2 /g-C 3 N 4 Nanofibers for Efficient Photocatalytic Degradation Performance
Russian Journal of Physical Chemistry A(2023)
Abstract
A serials of nanofibers with different contents of CeO 2 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 CeO 2 /g-C 3 N 4 composites were evaluated using tetracycline hydrochloride under simulated solar light illumination. When the loading amount of CeO 2 was 5.0 wt %, the composite showed the highest catalytic activity, which was 5.8 times that of porous g-C 3 N 4 . The enhanced photocatalytic properties of CeO 2 /g-C 3 N 4 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.
