摘　　要：纳米TiO2具有很好的光催化活性,对比研究了玻璃纤维、多孔硅胶、S iO2、分子筛等作为载体材料对纳米TiO2的固定,比较了各种材料对纳米TiO2的负载量及负载条件,相对来说,玻璃纤维的负载量最大。以甲基橙为模拟物,测定了各种固定化纳米TiO2的光催化性能,负载量最大的玻璃纤维表现出最好的催化活性。Glass fiber, aperture aerosil, SiO2 and molecular sieve were compared when used as the carrier materials in immobilizing nanometer TiO2. Comparatively, glass fiber had the highest carrying capacity. With methyl orange as the simulacrum of the photocatalytic reac- tion, the photocatalytic properties of the nanometer TiO2 immobilized by various carriers were determined. Glass fiber, which had the highest carrying capacity, showed the highest catalystic activity.
