ZnCH3COO2 + PVP-C2H5O4Si + PVP-SnCl4 + PVP-TiOC4H94 + CH3COOH + PVP precursor composite fibers have been fabricated through self-made electrospinning equipment via electrospinning tech-nique. ZnO-SiO2-SnO2-TiO2 composite nanofibers were obtained by calcination of the relevant precursor composite fibers. The samples were characterized by thermogravimetric-differential thermal analysis TG-DTA, X-ray diffractometry XRD, Fourier transform infrared spectroscopy FTIR, and Scanning electron microscopy SEM. TG-DTA analysis reveals that solvents, organic compounds and inorganic in the precursor composite fibers are decomposed and volatilized totally, and the mass of the samples kept constant when sintering temperature was above 900?C, and the total mass loss percentage is 88%. XRD results show that the precursor composite fibers are amorphous in structure, and pure phase ZnO-SiO2-SnO2-TiO2 com-posite nanofibers are obtained by calcination of the relevant precursor composite fibers. FTIR analysis manifests that pure inorganic oxides are formed. SEM analysis indicates that the width of the precursor composite fibers is ca. 1.485 ± 0.043 μm. The width of the ZnO-SiO2-SnO2-TiO2 composite nanofibers is ca. 1145.098 ± 68.093 nm.
