摘    要: 以自制的贝壳基规整吸附体为载体,采用浸渍煅烧法制备了Fe 3+x-TiO2/Shell光催化剂。采用XRD、SEM-EDS和UV-Vis等技术对制备的Fe 3+x-TiO2/Shell光催化剂进行表征。以石油为降解对象,考察了Fe3+掺杂量、Fe 3+x-TiO2/Shell的负载次数及光照时间对Fe 3+x-TiO2/Shell光催化活性的影响。结果表明,Fe3+掺杂量为0.7%(m(Fe3+ )/m(TiO2)×100%)、Fe 3+0.7-TiO2负载次数为4次时,制备的Fe 3+0.7-TiO2/Shell光催化剂的光催化活性最高,300 W碘钨灯照射16 h,石油的光催化降解率达76%。

Abstract:Fe 3+x-TiO2/Shell photocatalysts with Fe3+ doped TiO2 film supporting on the regular structured seashell-based adsorbent were successfully synthesized by wet-impregnation-calcination method, and characterized by XRD, SEM-EDS and UV-Vis techniques. The effects of Fe3+ doped amount(x), coated times of Fe 3+x-TiO2 and illumination time on photocatalytic activity of Fe 3+x-TiO2/Shell for oil degradation were investigated. The results showed that the Fe 3+x-TiO2/shell with four coated times ofFe 3+x-TiO2 possessed the highest photocatalytic activity for oil degradation. After 16 h illumination with 300 W iodine-tungsten lamp, the oil degradation rate on the seawater reached 76%.
