Preparation and morphology controlment of one-dimensional zinc oxide nano-fibers
To prepare ZnO nanofibers with homogeneous and good morphology,the microscopic morphologies of nanofibers were adjusted by changing the solvents and calcination temperature of the precursor solution during the electrostatic spinning process.The ZnO nanofibers were characterized by scanning electron microscopy,X ray diffractometer and automatic gas adsorption instrument.The results showed that the ZnO nanofibers were with homogeneous morphologies when acetylacetone/N,N-dimethylformamide(DMF)mixture solution was used as the solvent of the precursor and the heat treatment temperature was at 500 ℃.The ZnO nanofibers were with average diameter of 200 nm,showing a uniform particle stacking shape and a specific surface area of 9.03 m2/g.The ZnO nanofibers had excellent absorption performance to UV light and the forbidden bandwidth was up to 3.18 eV.
