Fabrication and Photocatalytic Properties of MgFe2O4/rGO/V2O5 Heterostructure Nanowires

Development of green clean energy has become one of promising challenge recently. One popular application of solar energy is photocatalysis, where semiconductors were used as photocatalyst to convert solar light into photoelectrons/holes. Photocatalysis technology has been widely applied for water splitting and degradation. Tetracycline (TC) is a sort of popular anthropogenic emissions in wasted water, which will caused seriously environmental pollution. A novel MgFe2O4/GO/V2O5 heterostructure has been successfully prepared by electrospinning method and high temperature chemical vapor deposition. The structure of samples was systematically characterized by XRD patterns and SEM images. The morphology of MgFe(2)O(4)and MgFe2O4/GO/V2O5 was both uniform one-dimensional nanowires. The degradation ratios of TC by MgFe2O4 and MgFe2O4/GO/V2O5 were 18% and 40%, respectively. The enhanced photocatalytic property of MgFe2O4/GO/V2O5 indicated that the GO and V2O5 played an important role in the separation of photogenerated holes and electrons. Therefore, MgFe2O4/GO/V2O5 can be used efficient photocatalyst for sewage treatment in environment.
