Nanofibras de TiO2 /ZnO preparado por calcinação de fibras precursoras de poli (acetato de vinila), isopropóxido de titânio e pó nano de zinco produzidos por eletrofiação técnica estudada. A estrutura e morfologia das nanofibras de TiO2/ZnO e fibras precursores foram caracterizados por microscopia eletrônica de varredura (SEM), Microscopia eletrônica de varredura de emissão de campo equipada com espectroscopia de raios-X dispersiva (FESEM-EDS), Espectroscopia de Fourier Transform Infrared (FTIR) e difração de raios X (DRX). A análise de XRD mostrou a formação de estruturas de cristal de óxido de titânio (anatase) e zinco (wurtzita hexagonal), depois de fibras precursoras de calcinação a 500 °C. Micrografias mostram que tanto o precursor e fibras nanofibras uniformes formar redes e boa morfologia. Estas nanofibras de dióxido de titanio /óxido de zinco apresentam bom área de superfície e diâmetros de 200 nm apropriados que poderiam ser de aplicativo potencial no campo de energia renovável, em particular, para a fabricação de celas solares.Downloads
