Photocatalytic Activities of Layered Intercalated Materials H2Fe2Ti3O10/TiO2 under UV and Visible Light Irradiation

Abstract

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.
