“…The micrograph shows that two forms of nanoparticles are present. Dark contrast particles showed a spherical form with a random orientation and an average size of >50 nm, consisting in a CCMF ferrimagnetic phase in the structure [36]. For the CCMF sample a closer investigation into the HR-TEM image shows the presence of two types of crystallites that can be well correlated to the XRD observations.…”

In the current research, Cu0.5Co0.3Mo0.2Fe2O4 mixed ferrite nanoparticles have been synthesized using Co-precipitation method. XRD patterns show the development of polyphasic copper, cobalt and molybdenum mixed spinel composition. The particle size of ferrite system is 16nm and they are nanoparticles. The lattice constant was determined to be 8.368 Å used for the highest peak (311). FTIR spectroscopy shows the lower octahedral and higher tetrahedral frequency alignment of ions in the spinel ferrite leading to the octahedral 550 cm− 1 and the tetrahedral 471 cm− 1 vibration modes. TEM micrographs showed spherical morphology and their particle size less than 50 nm, which correlated XRD crystallite size. VSM shows excellent ferrimagnetic properties because of higher coercivity (985.29 G). These higher coercivity materials can make cathode content for Li-ion batteries.

“…Ciocarlan et al [117] evaluated the structural, morphological, and photocatalytic properties of magnetic nanoparticles Co 0.5 Zn 0.25 M 0.25 Fe 2 O 4 /TiO 2, where M represent Ni 2+ , Cu 2+ , and Mn 2+ ions. XRD patterns for TiO 2 -based magnetic nanocomposites showed that the introduction of TiO 2 into the magnetic nanoparticles affected their structural properties (Figure 12).…”

“…Finally, in terms of photocatalytic activity, the results demonstrated that approximately 80% and 75% of methylene orange (MO) and methylene blue (MB) were effectively degraded by Co0.5Zn0.25Ni0.25Fe2O4/TiO2. The authors attributed the good photocatalytic activity to the Ni 2+ ions and synergistic effect in combination with Co 2+ ions [117]. This section may be divided by subheadings.…”

Removal of Organic Dyes from Water and Wastewater Using Magnetic Ferrite-Based Titanium Oxide and Zinc Oxide Nanocomposites: A Review

et al. 2021

Heterogeneous photocatalysis using titanium dioxide (TiO2) and zinc oxide (ZnO) has been widely studied in various applications, including organic pollutant remediation in aqueous systems. The popularity of these materials is based on their high photocatalytic activity, strong photosensitivity, and relatively low cost. However, their commercial application has been limited by their wide bandgaps, inability to absorb visible light, fast electron/hole recombination, and limited recyclability since the nanomaterial is difficult to recover. Researchers have developed several strategies to overcome these limitations. Chief amongst these is the coupling of different semi-conductor materials to produce heterojunction nanocomposite materials, which are both visible-light-active and easily recoverable. This review focuses on the advances made in the development of magnetic ferrite-based titanium oxide and zinc oxide nanocomposites. The physical and magnetic properties of the most widely used ferrite compounds are discussed. The spinel structured material had superior catalytic and magnetic performance when coupled to TiO2 and ZnO. An assessment of the range of synthesis methods is also presented. A comprehensive review of the photocatalytic degradation of various priority organic pollutants using the ferrite-based nanocomposites revealed that degradation efficiency and magnetic recovery potential are dependent on factors such as the chemical composition of the heterojunction material, synthesis method, irradiation source, and structure of pollutant. It should be noted that very few studies have gone beyond the degradation efficiency studies. Very little information is available on the extent of mineralization and the subsequent formation of intermediate compounds when these composite catalysts are used. Additionally, potential degradation mechanisms have not been adequately reported.

“…The water pollution is a serious threat to human health and aquatic life all over the world (Fiorenza et al 2018). The large amount of water used in textile industry for various processes released to aquatic environment along with toxic organic dyes (Ciocarlan et al 2018). The products resulting from photochemical oxidation and hydrolysis reactions occurred in wastewater containing organic dyes are harmful to aquatic life.…”

The tin dioxide nanoparticles (SnO 2 NPs) were fabricated via eco-friendly process using Daphne mucronata (D. mucronata) leaves extract as capping and reducing agent. The N 2 adsorption/ desorption experiment was performed to determine the surface area by Brunauer-Emmett-Teller (BET) method and S BET was found to be 147 m 2 g −1 . The crystalline nature and lattice parameter was studied by x-ray diffraction (XRD) and calculated crystallite size is 15.63 nm. The surface morphology was examined by scanning electron microscopy (SEM) and the estimated average particle size is 64 nm. The percentage composition and purity of the SnO 2 NPs was determined by energy dispersive x-ray (EDX). The raman active modes were identified by using raman spectroscopy while functional groups upon the surface were studied by using fourier transform infrared (FTIR) spectroscopy. The photocatalytic performance of SnO 2 NPs was examined against Rhodamine 6G (R6G) and 99.70% rhodamine 6G (R6G) were degraded in 390 min with the degradation rate of 0.0148 per min. The SnO 2 NPs were screened against the selected microorganisms and the order of antimicrobial activity is given as; Gram negative bacteria (GNB)>Gram positive bacteria (GPB)>fungi.
