“…Figure 2 displays the UV-vis diffuse reflectance spectra of the prepared samples. From the figure, we can see that CuFe 2 O 4 demonstrates a wide light absorption throughout the whole UV-vis region, which is in agreement with previous reports [32,33], and the MnTPP dye exhibits a strong Soret band at 455 nm and two weak Q bands at 570 and 610 nm, respectively [34]. The spectrum of the MnTPP/CuFe 2 O 4 composite exhibits broad absorption ability in visible light region, with the characteristic absorption of MnTPP bands centered at 464 and 614 nm.…”

A novel composite composed of (5, 10, 15, 20-tetraphenyl) porphinato manganese sensitized p-type CuFe 2 O 4 was developed for constructing the photocathode of a tandem photoelectrochemical (PEC) cell. The prepared material was characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and UV-vis diffuse reflectance spectroscopy (DRS). Light-driven water splitting to produce hydrogen can be achieved through the PEC cell, and the results show that H 2 and O 2 can be collected separately at low applied bias. This work demonstrates that manganese porphyrin sensitized CuFe 2 O 4 is an effective hybrid material for building the photocathode of a PEC cell for solar water splitting to produce H 2 .

Zn-doped CuFe2O4 nanoparticles (NPs) were eco-friendly synthesized using plant extract. These nanoparticles were characterized by X-ray diffraction, Fourier-transform infrared spectroscopy, scanning electron microscope (SEM), energy-dispersive X-ray spectroscopy and thermal gravimetric analysis (TGA). SEM image showed spherical NPs with size range less than 30 nm. In the EDS diagram, the elements of zinc, copper, iron, and oxygen are shown. The cytotoxicity and anticancer properties of Zn-doped CuFe2O4 NPs were evaluated on macrophage normal cells and A549 lung cancer cells. The cytotoxic effects of Zn-doped CuFe2O4 and CuFe2O4 NPs on A549 cancer cell lines were analyzed. The Zn-doped CuFe2O4 and CuFe2O4 NPs demonstrated IC50 values 95.8 and 278.4 µg/mL on A549 cancer cell, respectively. Additionally, Zn-doped CuFe2O4 and CuFe2O4 NPs had IC80 values of 8.31 and 16.1 µg/mL on A549 cancer cell, respectively. Notably, doping Zn on CuFe2O4 NPs displayed better cytotoxic effects on A549 cancer cells compared with the CuFe2O4 NPs alone. Also spinel nanocrystals of Zn-doped CuFe2O4 (~ 13 nm) had a minimum toxicity (CC50 = 136.6 µg/mL) on macrophages J774 Cell Line.

“…According to which, due to dilution in A sub‐lattice, the A–B sub‐lattice interaction is no longer strong and causes a strong B–B sub‐lattice interaction . This causes a disturbance in the spin magnetic moment on the B‐site and hence spin canting occurs which leads to a decrease in M s value . This clearly indicates that the nanoparticles exhibited a superparamagnetic property.…”

“…Of the various spinel ferrites, copper ferrite (CuFe 2 O 4 ) is one of the most studied by various experimental techniques because of the relatively small energy difference between Cu 2+ ions at the tetrahedral (A) and octahedral (B) sites, and cation rearrangement is probable and strongly dependent on the microstructure, calcination temperature, cooling rate and other parameters . Incorporation of various substituents of magnetic and nonmagnetic nature like Zn, Al, Ni and Co, Ti, etc., has been done in copper ferrite to transform the properties. However, to the best of our knowledge, zirconium has not been substituted in copper ferrite.…”

The effect of varied zirconium content on the structural, morphological, magnetic, optical, thermal and catalytic properties of nanoparticles of the ferrite Cu1 − xZrxFe2O4 (x = 0, 0.5, 1) was investigated. The mixed ferrite was synthesized by the auto‐combustion method using nitrates of respective metals and citric acid as a chelating agent. The as‐prepared nanoparticles showed dual benefits. They were employed as a heterogeneous catalyst for one‐pot synthesis of polysubstituted pyridine derivatives as well as for catalytic degradation of industrial waste dyes such as methylene blue (MB). The highlight of the research reported is the catalytic degradation of industrial waste (MB) with high efficiency in eluent of a wide range of pH (3–13). The proposed nanoparticles arguably offer certain great advantages that include: low cost, facile nature, anti‐leaching property, magnetic recoverability and recyclability. The characterization of the as‐synthesized nanoparticles was done using various techniques. The leaching study was carried out using inductively coupled plasma optical emission spectroscopy. The formation of organic products was confirmed using Fourier transform infrared and 1H NMR spectroscopies and examination of degradation products of MB dye was carried out using mass spectrometry and UV–visible spectroscopy.
