摘　　要：Sulfated zirconia/silica(SZ/SiO2) complex nanofibers were prepared by combining electronspinning technique and sol-gel method.First,a silica sol was electrospun at a voltage of 12 kV,then the as-electrospun silica nanofibers were immersed into a sulfated zirconia sol afterwards with a thermal treatment to obtain the SZ/SiO2 complex nanofibers.These fibers were examined by SEM,TEM,FTIR, XRD and SPS.The results indicate that the SZ nanopaticles with the average diameter of about 8 nm were disspered on the surface of silica fibers which had an average diameter of about 170 nm.The complex nanofibers had an amorphous structure.The observation of the surface-related transitions at the SPS spectrum indicates the presence of positive charges on the surface of the complex fibers.Sulfated zirconia/silica （SZ/SiO2 ） complex nanofibers were prepared by combining electronspinning technique and sol-gel method. First, a silica sol was electrospun at a voltage of 12 kV, then the as-electrospun silica nanofibers were immersed into a sulfated zirconia sol afterwards with a thermal treatment to obtain the SZ/SiO2 complex nanofibers. These fibers were examined by SEM, TEM, FHR, XRD and SPS. The results indicate that the SZ nanopaticles with the average diameter of about 8 nm were disspered on the surface of silica fibers which had an average diameter of about 170 nm. The complex nanofibers had an amorphous structure. The observation of the surface-related transitions at the SPS spectrum indicates the presence of positive charges on the surface of the complex fibers.
