TixSn1-xO2 binary hollow shaped nanofibers were synthesized for photocatalysts by the impregnation, electro-spinning, and calcination by using tin chloride (SnCl2) and different weight ratios of titatium tetraisopropoxide (TTIP) as precursors. The resultant samples were investigated by using field emmision scanning electron microscopy (FE-SEM), ultra high resolution field-emission scanning electron microscope (UHR FE-SEM) with energy dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), and thermogravimetry ananlysis (TGA). The results showed that in the case of the optimum weight ratio of the Ti precursor, uniformly distributed TixSn1-xO2 binary hollow nanofibers were successfully formed. The highest degradation ratio was about 85 % at 70 min using TixSn1-xO2 photocatalysts, which exhibited 3.5 times than that of TiO2. |
