Magnetic composite ZnFe2O4/SrFe12O19: Preparation, characterization, and photocatalytic activity under visible light

Fabrication of ZnFe2O4 films and its application in photoelectrocatalytic degradation of salicylic acid

“…Many photoelectrodes such as TiO 2 , ZnO, SrTiO 3 and BiOCl in the powdered form have been attracting considerable attention in the photocatalysis. However, it was difficult to separate out the catalysts from a liquid solution after reaction, which probably produced secondary pollution and increased costs [4]. Therefore, an alternative way is to use supported oxide semiconductor thin films as a photocatalyst.…”

Structural and Magnetic Properties of Hydrothermal Spinel Ni0.4Zn0.6Fe2O4 Ferrites

“…From the figure, the characteristic absorption peaks of tetrahedral and octahedral Fe-O stretching band in NZ-700 are at around 583.8 cm -1 and 426.7 cm -1 [15] . However, after sintered at 900 °C, the corresponding peaks shift slightly to the low wavenumber 579.5 cm -1 and 422.2 cm -1 , respectively, suggesting a strengthening of chemical polarization of the internal chemical bonds after sintering at higher temperature 16 . Clearly, compared with NZ-700, the structural change in NZ-900 after sintering at 900 °C was confirmed by the FTIR spectra.…”

Preparation and Properties of SrFe12O19/ZnFe2O4 Core/Shell Nano-powder Microwave Absorber

“…So the heavier material showed less bright, and that the low molecular mass material displayed more bright [9][10].…”
