摘要: 将电纺丝技术与溶胶-凝胶技术相结合, 制备了SZ粒子分布于SiO2纤维外壁的硫酸化的二氧化锆/二氧化硅复合纤维. 与常见的SZ复合催化剂相比, 采用SiO2纤维负载SZ不仅可以解决粉体材料带来的难以与反应体系分离等弊病, 同时功能粒子SZ分布与纤维外壁的结构也提高了功能粒子的利用率.

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.
