【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。更多还原

【Abstract】 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 reaction,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.更多还原
