Abstract

Abstract: 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.
