摘要: In this study, nanofiber mats consisting of two potential metal oxides were produced by electrospinning technique. An aqueous solution zinc acetate dihydrate and germanium isopropoxide was mixed with polyvinyl alcohol to prepare a sol–gel that electrospun at 20 kV. The obtained dried under vacuum 80 °C for 24 h then calcined in air different temperatures soaking times. Physiochemical characterizations have affirmed nanofibers composed oxide-germanium dioxide (ZnO–GeO2) can be prepared calcination temperatures. Scanning electron microscopy (SEM), transmission (TEM), the Brunauer–Emmett–Teller (BET) technique employed characterize as-spun product. specific surface area product decreased increases temperature. X-ray powder diffractometery (XRD) analysis used study chemical composition crystallographic structure. optical properties as-prepared ZnO–GeO2 also studied.
