Abstract

In this paper, synthesis of SnO2/ZnO composite hollow nanofibers using simple electrospinning method is reported. To improve the functional properties of composite hollow nanofibers, a different amount of ZnO precursor is added to the SnO2 precursor used in the solution. The structural and optical properties of produced nanofibers are studied using Scanning Electron Microscope (SEM), X-Ray (XRD) Diffraction, Ultraviolet-Visible Spectrophotometer (UV-Vis) and Fourier Transformed Infrared Spectrophotometer (FTIR). The XRD results show changes in the relative intensity of ZnO and SnO2 peaks with the increase or decrease amount of composite components. The FT-IR spectrum indicates a decrease in the relative band intensity of SnO2 with increasing ZnO in the composite. The UV-Vis spectra also show the flattening of the peaks by adding ZnO. Finally in the studying of photocatalytic properties with different ratios, the ratio of    shows the highest color decomposition, of the order of 62%, in 2 hours under UV irradiation.
