Influence of Fe3O4 Addition in TiO2 Catalyst on the Degradation Process of Methylene Blue

Abstract

Synthesis of composite titanium dioxide with iron oxide magnetic material (Fe3O4/TiO2 composite) has been successfully carried out by precipitation method. Photocatalytic performance test of this composite Fe3O4/TiO2 was performed for degradation process of the methylene blue solution with the experiment parameters consist of the solution pH, lighting time, type of light, amount of catalyst, and the concentration of methylene blue. The experimental results showed that the Fe3O4 addition in TiO2 catalyst can simplify recovery process of the catalyst, and able to broaden the absorption area up to visible light, so that the degradation process can be carried out with UV and visible light. Degradation of methylene blue by Fe3O4/TiO2 composite in under sunlight more effectively compared UV light.
