Hexagonal ferrite (MFe12O19, M=Sr, Ba, Cu, Ni, Pb) is a kind of semiconductor material with excellent performance and an important magnetic material, with high chemical and thermal stability, low cost, simple preparation process, excellent optical, magnetic, wave-absorbing, dielectric, photoluminescence properties and catalytic activities have been widely used in broadcast communication, information storage, aerospace, automatic control, catalytic synthesis, medicine and biology and many other fields. This paper focuses on the application of MFe12O19-based ferrite in the field of photocatalysis, and further discusses the effect of preparation method on the photocatalytic activity of MFe12O19-based photocatalysts. The application of MFe12O19-based photocatalysts in the degradation of dyes, drugs and persistent organic pollutants (POPs) was deeply revealed, and the photocatalytic mechanisms of single-phase MFe12O19, ion-doped MFe12O19 and MFe12O19-based composite photocatalysts were also explored. The relationship between photocatalytic activity and photoluminescence properties of MFe12O19-based photocatalysts have also been investigated. This review points out the direction for further research on the application of MFe12O19-based photocatalysts in the field of photocatalysis.

“…The electronhole recombination behavior can be identified through PL analysis. 54,55 As seen from Fig. 7(c), the PL spectra (measured at an excitation wavelength 340 nm) demonstrate clear broad PL emission peaks at around 350-600 nm, which originate from the electron-hole recombination behavior.…”

“…To further analyze the functional groups of PbFe 12 O 19 magnetic separation catalysts, Figure 3 shows the FTIR spectra of PbFe 12 O 19 magnetic separation catalysts. For all samples, two characteristic peaks at 3453 and 1638cm -1 were observed in the wavenumber range of 4000-1500cm -1 , which could be assigned to the stretching vibration of O-H bond and the bending vibration of H-O-H bond for the absorbed water, respectively [34,36,37] . The peak at 2365cm -1 could be ascribed to the adsorbed carbon dioxide [37,38] .…”

Objective: This study was performed to explore a new method to synthesize PbFe 12 O 19 magnetic separation catalysts and analyze its ultrasonic catalytic activity for the degradation of rhodamine B (RhB) dye under ultrasonic vibration.Methods: A polyacrylamide gel method was developed to synthesize the hexagonal lead ferrite (PbFe 12 O 19 ) magnetic separation catalysts with different Fe/Pb molar ratios and sintering temperatures. Results:The phase structure and composition of PbFe 12 O 19 magnetic separation catalysts altered with the change in the Fe/Pb mole ratio and sintering temperature. The color properties, energy band values and degradation percentages of PbFe 12 O 19 magnetic separation catalysts for the degradation of RhB dye under ultrasonic vibration were linearly independent of Fe/Pb mole ratio and sintering temperature. The maximum degradation percentage of 78.99% for the PbFe 12 O 19 magnetic separation catalysts for the removal of RhB from wastewater was found at 2g/L of initial catalyst concentration, 50mg/L of initial dye concentration, and 180min of vibration time. Conclusion:The PbFe 12 O 19 magnetic separation catalysts exhibited high catalytic activity for the degradation of RhB dye under ultrasonic vibrations. Based on the experiment parameters, a neural network model was established to predict the effect of synthesis parameters on the degradation percentage of PbFe 12 O 19 catalysts. This work further confirmed that the neural network algorithm was available to predict the ultrasonic catalytic activity of semiconductor materials.
