Synthesis and characterization of MgFe2O4 nanoparticles and PEG-coated MgFe2O4 nanocomposite

Designing of Z‐Scheme MgFe2O4/Fe2O3 Coupled CoCr2O4 Heterojunction with High Photocatalytic Activity for the Removal of Tetracycline Hydrochloride in Wastewater

“…[33][34][35] For the MFO, the characteristic absorption band at 571 and 424 cm −1 can be ascribed to the Fe─O in Fe 2 O 3 and the Fe─O vibration of the octahedral site in spinel MFO, respectively. [36][37][38][39][40][41][42][43] It is worth noting that the Fe─O vibration of MFO is located at 567 cm −1 , and this characteristic peak almost coincides with the characteristic peak of Fe─O bond in Fe 2 O 3 , which is the main reason why this characteristic peak has a wider half-height width than the characteristic peak reported in the literature. [34] When 25 wt% of CCO was coupled with MFO, the characteristic peak at 424 cm −1 shifted slightly to 442 cm −1 , confirming the formation of a special heterojunction between the interface of MFO and CCO.…”

Targeting nanoplatform synergistic glutathione depletion-enhanced chemodynamic, microwave dynamic, and selective-microwave thermal to treat lung cancer bone metastasis

“…2 A) of the sample aligned with the spinel ferrite crystal structure (JCPDS card No.01-071-1232), confirming its chemical formula as MgFe 2 O 4 . The inverse spinel structure of MgFe 2 O 4 was determined by the distinctive peaks observed in the crystallographic planes (220), (311), (400), (511), and (440) [ 55 ]. The characteristic type-IV isotherms with H1 hysteresis loops validate the hollow and mesoporous structure of the MgFe 2 O 4 ( Fig.…”

Effect of Copper Doping on the Structural, Electrical, and Magnetic Properties of Mg-Co Ferrites

“…This result is consistent with the previous studies, which showed the magnetic properties are enhanced due to the cation substitution. In a study, Hoyos-Sifuenteset al have reported the synthesis of magnesium ferrite material (MgFe2O4) and a Ms value of 17 emu/g [24]. Balavijayalakshmiet al,in their work synthesized the cobalt substituted magnesium ferrites andreported an increase in saturation magnetization (Ms), remanent magnetization (Mr) and coercivity (Hc) as the concentration of cobalt substitution increases,attributed to the change in the concentration of cation distribution [25].Thus, the excellent magnetic behavior of the synthesized Cu-doped Mg-Co ferrites can be used for high frequency magnetic storage device applications.…”
