Preparation and Photocatalytic Property of Heterojunction AgI/AgBr/TiO2 Catalyst

doi:10.7517/j.issn.1674-0475.2010.05.334

Abstract

Abstract: A novel AgI/AgBr/TiO₂ photocatalyst was synthesized by ion exchange of AgBr/TiO₂ substrate prepared via deposition-precipitation method.AgI/AgBr/TiO₂ was characterized by XRD and UV-Vis.The photocatalytic activity of AgI/AgBr/TiO₂ was measured with methyl orange(MO) as dye model under the visible light condition(500 W,λ>420 nm).The results showed that AgI broadened the light absorption range of AgBr/TiO₂ catalyst in visible light area and raised the photocatalytic activity of AgBr/TiO₂.The maximum of photocatalytic activity of AgI/AgBr/TiO₂ could be obtained when the AgI formation was 5% of AgBr.AgI/AgBr heterojunction was beneficial to separate the photogenerated elections and holes and then raised the photocatalytic activity of AgI/AgBr/TiO₂.

Key words: photocatalysis, methyl orange, AgI/AgBr/TiO₂ photocatalyst
