Photocatalytic degradation of methylene blue on magnetically separable MgFe{sub 2}O{sub 4} under visible light irradiation

Abstract

A magnetically separable single-phase MgFe{sub 2}O{sub 4} photocatalyst with a spinel crystal structure was synthesized by using the solid-state reaction method. The formation of spinel structure is confirmed by X-ray diffraction and Fourier transform infrared spectroscopy. The magnetic measurements showed that the photocatalyst material can be separated from water when an external magnetic field is added and redispersed into water solution after the external magnetic field is eliminated. It is one of the promising photocatalysts for waste water treatment. The photocatalytic activity of MgFe{sub 2}O{sub 4} was investigated by using the photo-decomposition of methylene blue dye under visible light. The photoelectrochemical property of the MgFe{sub 2}O{sub 4} was studied by measuring their photocurrent–potential behavior in 1 M NaOH electrolyte under AM 1.5100 mW cm{sup −2} illumination. - Graphical abstract: Highly efficient magnetically separable MgFe{sub 2}O{sub 4} photocatalyst for organic based impurities decomposition as well as for the production of H{sub 2} gas was synthesized and characterized successfully (a) MgFe{sub 2}O{sub 4} photocatalyst in polluted water, (b) The photocatalyst (MgFe{sub 2}O{sub 4}) is being attracted toward magnetic field for separation, (c) Hysteresis loop of MgFe{sub 2}O{sub 4} showing magnetic behavior.
