“…The hydrothermal synthesis was carried out and 10–80 nm spherical clusters of ZnFe 2 O 4 were prepared, which were able to degrade 99.66% of direct red 81 dye after 2 h of solar irradiation. Tatarchuk et al [ 71 ] used quince fruit extract to dissolve metal nitrate, where the obtained solution was heated for 30 min to evaporate. The formed gel ignited by itself and burned slowly with large amounts of gases.…”

Zinc ferrite is a type of photocatalytic material with high physicochemical stability, narrow band gap, high carrier separation efficiency, high porosity, and paramagnetism, which makes it easy to recover. Thus, zinc ferrite is widely used as a photocatalyst in water treatment. In this paper, the preparation principles as well as the advantages and disadvantages of typical methods used to prepare zinc ferrite including hydrothermal, co-precipitation, sol-gel, and other novel methods such as biosynthesis have been summarized. Modification methods such as elemental doping, composite formation, and morphological modification have been highlighted. Using these modification methods, the catalytic activity of zinc ferrite toward the photocatalytic degradation of organic pollutants in water has been enhanced. Biosynthesis is regarded as a promising preparation method that uses biological materials instead of chemical materials to achieve the large-scale preparation of zinc ferrite using low cost, energy efficient, and environmentally friendly processes. Meanwhile, the combination of multiple modification techniques to enhance the photocatalytic performance of zinc ferrite will be an important research trend in the future.

Individual rod diameters of 40-80 nm (mean 60 nm with a normal variation of 9.74 nm) and rod lengths of 4-11 µm (mean 8 µm with a normal variation of 1.87 µm) are found in regularly produced nanorod bundles [16]. EDX investigation was used to identify the elemental composition and phase clarity of the samples, and the spectrum is given in Figure 5…”

Microwave heating (MHM) and mutated sol-gel (SGM) mechanisms were used to effectively create CuO samples with two dissimilar morphologies, such as nanoparticles (CuO-NPs) and nanorods (CuO-NRs), using Mussaendafrondosalinn plant extract as the bio-reducing operator. X-ray powder diffraction (XRD), scanning electron microscopy (SEM), and energy-dispersive X-ray (EDX) investigations were used to analyze the sample's structure, pureness, and morphological characteristics. UV-Visible diffuse reflectance (DRS) and photoluminescence (PL) spectroscopy methodologies were used to analyze optical properties and calculate bandgap energy. The bandgap of the samples was measured using the Kubelka-Munk mechanism, and it was found to be 2.74eV and 2.33eV for CuO-NPs and CuO-NRs, correspondingly. CuO-NPs and CuO-NRs were investigated for antibacterial activity versus each Gram-positive and Gram-negative microorganisms using a modified disc diffusion method. When correlated to the sample CuO nanorods, the antibacterial study confirms that the sample CuO nanoparticles are high-grade antibacterial agents. Using solar lighting, the photocatalytic activity of CuO nano-reactants (CuO-NPs and CuO-NRs) for the degradation of methylene blue (MB) dye was investigated, and the findings revealed that CuO-NPs with tinier particle sizes degraded MB more than CuONRs.

“…Actually, the type and size of the cations as well as their rearrangements have a profound effect on the ferrite characteristics [13][14][15][16]. In addition, researchers have used several additives to improve the photocatalyst's light-harvesting characteristics of these nanoferrites [17,18]. Among the most common types of additions, rare Earths like La, Y, NdK have a noticeable impact on ferrites' qualities thanks to their special f-electronic arrangement [19].…”

Improving effective and thrifty photocatalysts was deemed an outstanding approach for pollution handling. Here, a novel magnetic Co0.5Mg0.5LaxFe2-xO4 nanoparticle photocatalysts were synthesized via a combustion approach for the harmful methylene blue (MB) dye degradation. These samples were labeled as Co0.5Mg0.5Fe2O4 (CMLF0), Co0.5Mg0.5La0.03Fe1.97O4 (CMLF1), Co0.5Mg0.5La0.06Fe1.94O4 (CMLF2), Co0.5Mg0.5La0.09Fe1.91O4 (CMLF3), Co0.5Mg0.5La0.12Fe1.88O4 (CMLF4), and Co0.5Mg0.5La0.15Fe1.85O4 (CMLF5). A sequence of characterizations, including XRD, STEM, and UV–Vis-DRS, was exploited to examine the structure, morphology, constituent elements, and optical features of the CMLF ferrite nanoparticles. Despite the substitution process, an amazing decrement result for the lattice parameter (8.3748 to 8.3610 Å) and crystallite size (21.87 to 13.95 nm) is a large La cation at the expense of a smaller Fe one. The band-gap behavior of the CMLF nanoferrites is unique; it increases from 1.528 eV at the CMLF0 to 1.547 eV at the CMLF3 and decreases to 1.526 eV at the CMLF4 and 1.520 eV at the CMLF5. Two justifications accounted for this behavior. The nanoferrite CMLF5 has the highest photodegradation efficiency, 96.09 %, after 60 minutes. Three hypotheses were introduced to explain this result. After five cycles, the degradation efficiency of the nanoferrite CMLF5 maintained its high performance with 95.09 %, 94.87 %, 94.76 %, 93.59 %, and 93.44 %, respectively. These outcomes validate the outstanding photocatalytic efficiency, recyclability, and stability of the CMLF5 photocatalyst in its task to degrade the harmful MB dye, making it acceptable for wastewater treatment applications.
