“…Thus, the higher surface area of the sample LaMgFe-4 may lead to higher PCD efficiency (90.53 %) than other samples [39,49,55]. In addition, the amount of the dispersion of particles per volume in the solution will increase, which results in the enhancement of the photon absorbance [41,45,56].…”

“…It may be because the magnetic nature of Fe 3+ (5 μB) ions was replaced by the nonmagnetic nature of [43]. This is due to an increase in the disorder of the magnetic moment orientation within various sites when the ratio of surface/volume increases [44,45].…”

“…It can be easily recovered by applying external magnetic field and reused several times. Our research group has reported photocatalytic degradation (PCD) of 4-chlorophenol (4-CP) and methylene blue (MB) using spinel ferrites and metal sulfides nanocatalysts [40][41][42][43][44][45][46][47][48][49]. However, to the best of our knowledge, there is no literature available for the PCD of methylene blue by LaMg x Fe 1−x O 3−δ nano-photocatalysts.…”

Nanostructured perovskite mixed metal oxides, LaMg x Fe 1−x O 3−δ (x = 0.0, 0.2, 0.4, 0.6, 0.8, and 1.0), were synthesized successfully by a simple sol-gel route. The formation of single-phase perovskite oxides structure was confirmed by powder X-ray diffraction (XRD) analysis. The average crystallite size of the samples was evaluated using Sherrer's formula. The presence of functional groups and metal oxide bonds was confirmed by Fourier transform infrared (FT-IR) analysis. Brunauer-Emmett-Teller (BET) surface adsorption studies showed better surface area of the compositions, which was further, evidenced by scanning electron microscopy (SEM) analysis. Room temperature vibrating sample magnetometer (VSM) analysis was confirmed that the superparamagnetic nature and the magnetization values decreased with increase in Mg-dopant. The samples were subjected to dc electrical conductivity studies at room temperature. The dc resistance measurements as a function of relative humidity (RH) at 5, 31, 51, 79, and 98 % were carried out on sintered discs at 25 • C under static conditions, which sensitivity factor S f (R 5% / R 95% ) A. Manikandan were calculated for LaMg x Fe 1−x O 3−δ . The temperaturedependent conductance was also carried out in the range of 100-300 • C as suggested, and the activation energy was determined. Sample LaMgFe-4 (x = 0.6) possessed the highest humidity-sensing factor (12,926.03 ± 387), while LaFeO 3 (x = 0) possessed the lowest sensitivity factor (41.66 ± 3). The response and recovery characteristics were studied for LaMgFe-4, which exhibited a very good narrow hysteresis loop. The photocatalytic degradation (PCD) of methylene blue (MB) dye was investigated under UVvisible light and the sample LaMgFe-4 showed better PCD efficiency than other samples, due to the smaller particle size and higher surface area.

“…With these unusual properties, nanomaterials have aroused a wide range of interest of researchers and the engineers. Recently, nanomaterials have been used for in varieties of fields [16,[19][20][21][22][23][24][25][26][27][28][29] , but few investigations were reported for preparing the STFs. Compared with silica submicron particles, silica nanoparticles have small size and large specific surface area, which can enhance the friction force among the particles.…”

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.
