New Insights into Mn(1−x)Zn(x)Fe(2)O(4) via Fabricating Magnetic Photocatalyst Material BiVO(4)/Mn(1−x)Zn(x)Fe(2)O(4)

BiVO(4)/Mn(1−x)Zn(x)Fe(2)O(4) was prepared by the impregnation roasting method. XRD (X-ray Diffractometer) tests showed that the prepared BiVO(4) is monoclinic crystal, and the introduction of Mn(1−x)Zn(x)Fe(2)O(4) does not change the crystal structure of BiVO(4). The introduction of a soft-magnetic...

description BiVO(4)/Mn(1−x)Zn(x)Fe(2)O(4) was prepared by the impregnation roasting method. XRD (X-ray Diffractometer) tests showed that the prepared BiVO(4) is monoclinic crystal, and the introduction of Mn(1−x)Zn(x)Fe(2)O(4) does not change the crystal structure of BiVO(4). The introduction of a soft-magnetic material, Mn(1−x)Zn(x)Fe(2)O(4), was beneficial to the composite photocatalyst’s separation from the liquid solution using an extra magnet after use. UV-vis spectra analysis indicated that Mn(1−x)Zn(x)Fe(2)O(4) enhanced the absorption intensity of visible light for BiVO(4). EIS (electrochemical impedance spectroscopy) investigation revealed that the introduction of Mn(1−x)Zn(x)Fe(2)O(4) enhanced the conductivity of BiVO(4), further decreasing its electron transfer impedance. The photocatalytic efficiency of BiVO(4)/Mn(1−x)Zn(x)Fe(2)O(4) was higher than that of pure BiVO(4). In other words, Mn(1−x)Zn(x)Fe(2)O(4) could enhance the photocatalytic reaction rate.
