Immobilization of BiFeO3 on Silica Fiber and its Photocatalytic Application

Uniform immobilization of BiFeO3 on silica fiber was successfully obtained by a combined impregnation method with carbon nanofibers (CNFs) template route. The physicochemical properties of the obtained material were characterized by means of X-ray diffraction, field emission scanning electron microscopy, and ultraviolet-visible diffuse reflectance spectroscopy. It turned out that BiFeO3 immobilized on silica fiber can exhibit visible light photocatalytic degradation of rhodamine B (RhB) to some extents. It is expected that such kind of material would possess many potential applications in photocatalysis.
