Photo-catalysis degradation of methyl orange as pollutant dye using dioxide magnetic Fe3O4/Al2O3/TiO2 nanostructure

Abstract

The application of photo-catalysis technologies using nanomaterials based TiO2 increased as an applied strategy in different industries in the recent years. In this regards and in the presence study, Fe3O4/Al2O3/TiO2 nanostructure with core/shell/shell shape was synthesized and characterized by FT-IR and SEM methods. After confirming of synthesized procedure for magnetic TiO2 nanomaterial, it used for photo-catalysis degradation of methyl orange dye under Uv light. The effective parameters in removal yield for optimization of photo-catalysis systems was investigated. Results showed 100% removal yield for methyl orange under condition of 3.3 gr/lit photo-catalyst at pH=7.0 and the presence of 30 ppm at 60 min was occurred. In addition and for nano-catalyst without between layer 44% yield was occurred. In conclusion, Fe3O4/Al2O3/TiO2 nanostructure showed better photo-catalysis behavior compare to Fe3O4/TiO2 nanostructure.
