Preparation and characterization of CuCrO2-CeO2 nanofibers by electrospinning method

In this study, CuCrO2-CeO2 nanofibers were prepared by the electrospinning method and the influences of different concentrations on the properties of CuCrO2-CeO2 nanofibers were studied. The electrospun fibers were heated at 700 degrees C for 1 h in a decompression environment of 1.1 Torr to generate the CuCrO2-CeO2 nanofibers. The crystalline phase of the nanofibers was analyzed by X-ray diffractometer, and both main diffraction peaks corresponded to the CuCrO2 and CeO2 planes. Furthermore, the morphology of the fiber surface was identified by field emission scanning electron microscope, transmission electron microscope, and energy-dispersive X-ray spectroscopy. For this study, the diameter of the CuCrO2-CeO2 nanofibers was approximately 70 nm to 90 nm. The optical properties were analyzed by ultraviolet/visible spectrometer, and the surface area was determined by Brunauer Emmett Teller method. The CuCrO2-CeO2 nanofibers had a high specific surface area of 14.28 m(2)/g. The energy bandgap of the CuCrO2-CeO2 nanofibers was estimated at 2.95 eV to 2.97 eV with various concentrations. The prepared CuCrO2-CeO2 nanofibers are a potential material for photocatalyst studies.
