Resumen
CAMARGO-SILVA,, Sandra M.; MUNOZ-PRIETO, Efrén; VERA-GRAZIANO, Ricardo y GOMEZ-PACHON, Edwin Y.. Fabrication of TiO2/ZnO nanofibers for energy storage applications. Orinoquia [online]. 2017, vol.21, suppl.1, pp.56-63. ISSN 0121-3709. https://doi.org/10.22579/20112629.431.
The TiO2 /ZnO nanofibers prepared by the calcination of polyvinyl acetate of precursor fibers, titanium isopropoxide and nano zinc powder produced by the electrospinning technique were studied. The structu-re and morphology of TiO2 /ZnO nanofibers and precursor fibers were characterized by Scanning Electron Microscopy (SEM), Field Emission Scanning Electron Microscopy coupled to Energy Dispersive X-ray spectroscopy (FESEM-EDS), Fourier Transform Infrared Spectroscopy (FTIR) and XRD (X Ray Diffraction). XRD analysis displayed crystalline structures of titanium oxides (anatase) and zinc (hexagonal wurzite), after calcining the precursor fibers at 500 °C. SEM microphotographs display that both precursor fibers and nanofibers form uniform networks and good morphology. These titanium dioxide / zinc oxide nanofibers get good surface area and appropriate 200 nm diameters which could potentially be applied in the renewable energy field, particularly for solar cells manufacturing.
