Multifunctional Mn0.5Zn0.5Fe2O4 Nanoparticle/PPy-PEG Structures for Synergistic Photo-Magnetic Hyperthermia Applications

“…Conversely, the peak at a higher binding energy of approximately 712.3 eV corresponds to the Fe 3+ ions bonded with the hydroxyl groups. 46 Figure 2j presents the X-ray photoelectron spectroscopy (XPS) spectrum of Zn 2p, revealing the presence of the Zn-oxidation state through the two peaks observed at 1021.6 and 1044.6 eV. 47 In the high-resolution XPS of Mn 2p, the corresponding Mn 2p 1/2 and Mn 2p 3/2 signals are observed at 653 and 641 eV, respectively, in an ∼2:1 peak area ratio marking that Mn is present in an oxidation state (Figure 2k,l).…”

“…The peaks observed at 709.8 and 711 eV can be attributed to the Fe 3+ cations with varying occupancies (either tetrahedral or octahedral) within the spinel ferrite structure. Conversely, the peak at a higher binding energy of approximately 712.3 eV corresponds to the Fe 3+ ions bonded with the hydroxyl groups Figure j presents the X-ray photoelectron spectroscopy (XPS) spectrum of Zn 2p, revealing the presence of the Zn-oxidation state through the two peaks observed at 1021.6 and 1044.6 eV .…”

Application of the Zn0.5Mn0.5Fe2O4–PMMA nanocomposite for efficient removal of complex organic pollutants

“…The as-obtained Zn 0.5 Mn 0.5 Fe 2 O 4 has lattice parameters and crystal volume of 8.211 Å, and 565.7 Å 3 , respectively, agreeing with the reported results in other studies. 43,44 To ensure that the formed nanoparticles are in the range of nanometric size, the crystallite size of the as-prepared sample was calculated by using Debye-Scherrer's formula as shown in eqn (3): 45…”

The crystallite size of the prepared particles was 14.22 nm.…”

A review on MnZn ferrites: Synthesis, characterization and applications

“…Most common soft ferrites are MnZn ferrites [47][48][49][50][51][52][53][54][55] and NiZn ferrites [56][57][58][59][60][61][62][63][64][65][66][67][68][69][70][71][72][73]. MnZn ferrites are more preferred as they have high permeability [74] and saturation magnetization [75]as compared to NiZn ferrites. Because of low value of resistivity of MnZn ferrites as compared to NiZn ferrites, these ferrites are used for low frequency applications [76][77][78].…”
