Abstract

In this research, C-TiO2@Fe3O4 magnetic NANOCOMPOSITE was prepared via a sol-gel method and the removal of DIRECT BLUE 71 pollution in precence of visible light has been investigated. In this NANOCOMPOSITE core is magnetic nanoparticles of magnetite and shell is the CARBON-doped TiO2. The surface morphology, structure, and crystalline phase of the NANOCOMPOSITEs were characterized using XRD, SEM and HRTEM techniques. Studies showed that the Fe3O4 core has inverse cubic spinel structure and in shell C-TiO2, TITANIUM DIOXIDE has the anatase structure. Photocatalytic activity studies showed that as-prepared NANOCOMPOSITEs had high photodegradating behavior (95%) to DIRECT BLUE 71 compared to the pure TiO2 nanoparticles. The effect of process parameters such as, catalyst loading, and initial concentration of DIRECT BLUE 71 on the extent of degradation was investigated. The photocatalytic activity remained 85% after three reusing.
