“…It is interesting to note herein that the size and the shape of the obtained particles depend on various parameters such as the quantity of precursors, the temperature or the duration of the heat treatment [13,18]. More than that, they depend on the oleic acid/ oleylamine ratio and the presence or absence of hexadecanediol.…”

“…To date, several synthesis methods of MNPs have been developed [13,14,15,16,17,18] in an effort to improve the magnetic properties by controlling the size, the morphology, and the composition of the obtained nanoparticles. Among these different routes of synthesis, we have found the co-precipitations, solvothermal, hydrothermal and thermal decomposition which are the most effective ones.…”

In this work, a successful synthesis of magnetic cobalt ferrite (CoFe2O4) nanoparticles is presented. The synthesized CoFe2O4 nanoparticles have a spherical shape and highly monodisperse in the selected solvent. The effect of different reaction conditions such as temperature, reaction time and varying capping agents on the phase and morphology is studied.Scanning transmission electron microscopy showed that the size of these nanoparticles can be controlled by varying reaction conditions. Both X-ray diffraction and energy dispersive X-ray spectroscopy corroborate the formation of CoFe2O4 spinel structure with cubic symmetry. Due to optimized reaction parameters, each nanoparticle was shown to be a single magnetic domain with diameter ranges from 6 nm to 16 nm. Finally, the magnetic investigations showed that the obtained nanoparticles are superparamagnetic with a small coercivity value of about 315 Oe and a saturation magnetization of 58 emu/g at room temperature. These results make the cobalt ferrite nanoparticles promising for advanced magnetic nanodevices and biomagnetic applications.

“…Discharge of inorganic and organic pollutants from varying industries including printing, textiles, food, and beauty products into environmental water resources has been a main environmental problem in all countries regardless of how they are developed. Up to date, different methods based on physical, chemical, and biological treatments such as membrane processes, reverse osmosis, photocatalytic degradation, photo-Fenton, ozonation, oxidation, biological, as well as electrochemical procedures have been used for remediation of industrial wastewaters (Barbusiński, 2005;Farré et al, 2005;Liu et al, 2007;Dogan and Turkdemir, 2012;Ioannou et al, 2013;Zheng et al, 2013;Suresh et al, 2014;Suresh et al, 2016;Jesudoss et al, 2017;Rajan et al, 2017;Kooshki et al, 2019;Peymani-Motlagh et al, 2019a;Peymani-Motlagh et al, 2019b;Rahimi-Nasrabadi et al, 2019;Sobhani-Nasab et al, 2019aSobhani-Nasab et al, 2019c). Among the most commonly mentioned methods which are subject to restrictions, photocatalytic degradation systems act as a smart tool, because it is simple, highly efficient, and inexpensive (Basith et al, 2014;Vijaya et al, 2017;Sedighi et al, 2018;Eghbali-Arani et al, 2018;Sobhani-Nasab et al, 2019d).…”

The new nanocomposite with various molar ratios along with magnetic properties was fabricated via precipitation (assisted by ultrasonic) procedure. The photocatalytic effects of methylene blue (∼90% degradation for optimized sample in 100 min) for finding the optimized sample performed under visible light irradiation. Moreover, the photo-antibacterial impacts of bacteria culture environments were found with an optimized sample that had effective destruction of bacteria in comparison to control group. The cytotoxicity properties of panc1 cells and magnetic behaviors of the obtained nanomaterials were evaluated and its IC50 was about 500 mg/L. As an initial step, the structural, morphological and magnetic characteristics of the fabricated nanocomposites were evaluated by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), X-ray diffraction (XRD), energy dispersive X-ray (EDX) and MAP, UV-visible diffuse reflectance spectroscopy (DRS), and vibrating sample magnetometry (VSM) approaches. Based on SEM results, the size of nanoparticles in fabricated nanocomposite was nearly 50-70 nm for Fe 3 O 4 /SiO 2 /TiO 2 and 80-100 nm for Fe 3 O 4 /SiO 2 /TiO 2 /CeVO 4 . XRD results showed that desired nanocomposites were truly synthesized without any impurities.

“…However, reusability tests showed a constant decrease in activity between the first and fifth cycle (from 95% to 70% degradation), connected with possible photocatalyst loss between the cycles as well as surface blocking and partial destruction of the composite mesostructured. Another photocatalyst was designed by Sobhani-Nasab et al, who prepared a BaFe 12 O 19 /Sm 2 Ti 2 O 7 structure in its bare and Ag-decorated forms [126]. It was found that Ag has a positive impact on the activity, resulting in 100% degradation of MB during 150 min of vis irradiation (400-770 nm).…”

Semiconducting materials display unique features that enable their use in a variety of applications, including self-cleaning surfaces, water purification systems, hydrogen generation, solar energy conversion, etc. However, one of the major issues is separation of the used materials from the process suspension. Therefore, chemical compounds with magnetic properties have been proposed as crucial components of photocatalytic composites, facilitating separation and recovery of photocatalysts under magnetic field conditions. This review paper presents the current state of knowledge on the application of spinel and hexagonal ferrites in heterogeneous photocatalysis. The first part focuses on the characterization of magnetic (nano)particles. The next section presents the literature findings on the single-phase magnetic photocatalyst. Finally, the current state of scientific knowledge on the wide variety of magnetic-photocatalytic composites is presented. A key aim of this review is to indicate that spinel and hexagonal ferrites are considered as an important element of heterogeneous photocatalytic systems and are responsible for the effective recycling of the photocatalytic materials.
