“…The hydrophilicity and magnetic properties of manganese ferrite NPs bring merits when formulating into a nanocarrier. However, surface functionalization is needed to ensure high drug loading capacity with superior controlled release behaviour [135] . For instance, carboxymethyl chitosan hydrogel functionalized manganese ferrite NP is able to load 67.2 % curcumin through the hydrogen bonding interaction.…”

The controlled released behaviour of manganese ferrite NPs is governed by the environmental pH where acidic environment promotes the release of drug through the binding with hydrogen bonds.…”

Iron‐based magnetic nanoparticles (MNPs) have been studied extensively for the past few decades. They have been applied in various applications, particularly in the biomedical sector. Due to their excellent physical and chemical properties, they have also been used widely in the agricultural sector. MNPs can be synthesized inexpensively and applied in large scale agricultural activities. This paper highlights the applications of iron‐based MNPs in the agricultural sector mainly as antimicrobial agents, plant growth promoters, site‐targeted delivery agents, nanosensors, detection and remediation for pesticide residue. Furthermore, the toxicity and transport of iron‐based MNPs in the soil‐plant system are also elucidated. These aspects have to be well‐understood before MNPs can be fully implemented effectively this pin the agricultural sector. Lastly, a hybrid nanomaterial, which is consisted of iron and magnesium oxide (MgO) nanoparticles (NPs), is proposed. This hybrid nanomaterial is expected to overcome the shortcomings of iron‐based MNPs.

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 harm and treatment of methyl blue (MB) were described, and the necessity for the removal of MB by magnetic nanomaterials was explained. Magnetic Ni-Mg-Co ferrites were prepared by the rapid combustion approach of an active nitrate solution and characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), Fourier transform infrared spectrometer (FTIR), energy dispersive spectroscopy, and vibrating sample magnetometer. Magnetic Ni 0.1 Mg 0.7 Co 0.2 Fe 2 O 4 nanoparticles prepared at 400 C with the saturation magnetization of 19.7 emu g À1 and the average diameter of about 15.2 nm were used to adsorb MB from the aqueous medium. The Brunauer-Emmett-Teller (BET) analysis showed that the specific surface area was 143.17 m 2 g À1 and the average pore size was 9.44 nm. The adsorption mechanism of MB onto magnetic Ni 0.1 Mg 0.7 Co 0.2 Fe 2 O 4 nanoparticles was studied, and the results revealed that the adsorption properties conformed the pseudo-second-order kinetics model due to the square deviation values (R 2 > 0.98), and Temkin model could describe the adsorption state of MB onto Ni 0.1 Mg 0.7 Co 0.2 Fe 2 O 4 nanoparticles, which suggested that the adsorption of MB onto Ni 0.1 Mg 0.7 Co 0.2 Fe 2 O 4 nanoparticles was monolayer-multilayer hybrid chemisorption mechanism. When the pH value exceeded 3, the adsorbance reached large value; while, the adsorbance was 97.6% of the initial adsorption value for seven cycles. The electrochemical impedance spectroscopy and cyclic voltammetry curves of MB adsorbed onto the nanoparticles before and after the adsorption were determined.
