摘要: 在高压汞灯辐照下,通过插入反应将H2Fe2Ti3O10与n-C3H7NH2/C2H5OH和TiO2溶胶制备出H2Fe2Ti3O10/TiO2插层复合物.插入TiO2的层状钙钛矿化合物H2Fe2Ti3O10在UV-vis辐照下表现出高活性.实验结果表明H2Fe2Ti3O10/TiO2作为光催化剂在可见光(λ>420nm)下辐照24h,降解甲基橙的速率为59.0;.与相同条件下降解率只有24;的商用光催化剂TiO2(Degussa P-25)相比,H2Fe2Ti3O10/TiO2表现出了更高的光催化活性.

Abstract: A new nanocomposite,H2Fe2Ti3O10/TiO2 was synthesized by the stepwise intercalation reactions of H2Fe2Ti3O10 with n-C3H7NH2/C2H5OH mixed solution and acid TiO2 colloid solution. H2Fe2Ti3O10,a layered perovskite type compound with TiO2-loading, exhibited a high activity for decomposition of methyl orange under UV and visible light irradiation.The experimental results showed that methyl orange was degraded with the decomposition ratio of 59.0; by using H2Fe2Ti3O10/TiO2 as photocatalyst under visible light(λ>420nm)irradiation for 24h. The H2Fe2Ti3O10/TiO2 possessed higher photocatalytic activity than those commercial titania powder(Degussa P-25) which showed the decomposition ratio just only 24; under same condition.
