dc.description.abstractSe estudiaron nanofibras de TiO2/ZnO preparadas por calcinación de fibras precursoras de poli (vinil acetato), isopropóxido de titanio y nano polvo de zinc elaboradas por la técnica de electrohilado. La estructura y la morfología de las nanofibras de TiO2/ZnO y fibras precursoras se caracterizaron por Microscopia Electrónica de Barrido (SEM), Microscopia Electrónica de Barrido de Emisión de Campo equipado con Espectroscopia Dispersiva de Rayos X (FESEM-EDS), Espectroscopia de Infrarrojo con Transformada de Fourier (FTIR) y Difracción de Rayos X (XRD). El análisis XRD mostró la estructura cristalina de los óxidos de titanio (anatasa) y de zinc (wurzita hexagonal), después de calcinar las fibras precursoras a 500 °C. Las microfotografías de SEM muestran que tanto las fibras precursoras como las nanofibras forman redes uniformes y buena morfología. Estas nanofibras de dióxido de titanio /óxido de zinc presentan buen área de superficie y diámetros de 200 nm apropiados que podrían ser de aplicación potencial en el campo de energía renovable, en particular, para la fabricación de celdas solares.spa
dc.description.abstractThe 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 structure 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.eng
