| One-dimensional or normal one-dimensional structure inorganic nanomaterials have potential application in electronics,photonics,mechanics areas and so on. The nanofibers have been attracted by many researchers and have become the hot study of nano-technology due to their superior optical, acoustic, electrical, magnetic, thermal and mechanical properties. The illuminant rare-earth oxide materials have been widely used in high-tech fields. The study of preparation, properties, and application of the rare-earth oxide nanofibers have become an important subject. In recent years, the electrospining combined with sol-gel is a relatively convenient and useful way to fabrication inorganic nanofibers. Against the back ground of preparation and application of one-dimensional nanomaterials, the article reports on the latest progress in research of one-dimensional naonomaterials and our research achievements with the emphasis of preparing one-dimensional nanomaterials. The contents are as follows:1. The TiO2-ZrO2 complex nanotubes were prepared by sol-gel coating of electrospining polymer fibers. PBS nanofibers were used as substrate, PBS-TiO2-ZrO2 coaxial nanofibers were fabricated using sol-gel coating technique to fill PBS nanofibers that were prepared by electrospining. The TiO2-ZrO2 complex nanotubes were obtained via calcining PBS-TiO2-ZrO2 coaxial nanofibers. SEM,TEM and TG techniques were performed to the nanotubes.2. The inorganic BaO-TiO2 nanofibers have been fabricated by sol-gel combined with electrospining method. PVP was used as substrate, ethanol was used as solvent, while barium acetate and Tetra-n-butyl titanate were used as precursor. The PVP/Ba(CH3COO)2/TiO2 composite nanofibers were fabricated by electrospining. The inorganic BaO-TiO2 nanofibers were obtained via calcining PVP/Ba(CH3COO)2/TiO2 composite nanofibers. TG, SEM, IR, and XRD techniques were performed to the organic and inorganic nanofibers.3. The inorganic Mn doped ZnO nanofibers have been fabricated by sol-gel combined with electrospining method. PVP was used as substrate, ethanol was used as solvent while Mn(CH3COO)2 and Zn(CH3COO)2 was used as precursor. The PVP/Mn(CH3COO)2/Zn(CH3COO)2 composite nanofibers were fabricated by electrospining. The inorganic Mn doped ZnO nanofibers were obtained via calcining PVP/Mn(CH3COO)2/Zn(CH3COO)2 composite nanofibers. TG, SEM, IR, XRD and Fluorescence spectrometer techniques were performed to the organic and inorganic fibers. The XRD indicated that the production structure was ZnMn2O4 crystalline.4.
