Abstract

In this study, iron-oxide (magnetite) synthesized by co-precipitation method and binary TiO2-Fe3O4 and ternary rGO-TiO2-Fe3O4 nanocomposites (called GTF) prepared by hydrothermal method. Crystal structure and bonds, studied by X-ray diffraction (XRD) and FTIR analysis respectively. The morphology of samples was studied by SEM. The average size of nanoparticles estimated ~12.3 nm and saturation magnetization of nanocomposites obtained by VSM, was 40.26 emu/g. The photocatalytic activity of synthesized nanocomposites determined by degradation of methyl orange under UV light irradiation. The ternary nanocomposites showed ~98.7 % degradation of methyl orange which has a remarkable improvement compared to TiO2-Fe3O4 binary nanocomposites with 84 % degradation.
