Spinel ferrite nanostructures have played significant roles in the development of materials science and technology. Spinel ferrite nanostructures possess not only promising magnetic properties but also high resistivity, stability, and low eddy current losses. The recent progress in the utilization of spinel ferrite nanostructures for water remediation is reviewed with special emphasis on the adsorption, transformation, degradation, and catalytic reduction of nitroaromatics. Then, the structure–property relationships and design considerations of spinel ferrite nanostructures for catalytic applications are discussed in detail. Insights into the details of the various removal processes on the model spinel ferrite nanostructures are provided with a basic concept of nitroaromatics remediation. Subsequently, reaction kinetics and mechanisms are classified and their advantages and disadvantages are described. Lastly, challenges and future perspectives of spinel ferrite nanostructures for their practical applications are presented. With further advancement, spinel ferrites have potential to be practically utilized for a wide range of applications such as water treatment plants.

“…MIPs are a class of polymers synthesized with target molecules as templates, which have a specific selective recognition function [ 16 , 17 ]. However, as most MIPs cannot achieve the purpose of the high-sensitivity detection of target molecules due to their poor electrical conductivity [ 18 ], the selection of nanomaterials with excellent conductivity to enhance the electrochemical signal is a problem that must be considered [ 19 , 20 , 21 ].…”

In view of the great threat of chloramphenicol (CAP) to human health and the fact that a few producers have illegally used CAP in the food production process to seek economic benefits in disregard of laws and regulations and consumer health, we urgently need a detection method with convenient operation, rapid response, and high sensitivity capabilities to detect CAP in food to ensure people’s health. Herein, a molecularly imprinted polymer (MIP) electrochemical sensor based on a dual-signal strategy was designed for the highly sensitive analysis of CAP in milk. The NiFe Prussian blue analog (NiFe-PBA) and SnS2 nanoflowers were modified successively on the electrode surface to obtain dual signals from [Fe(CN)6]3−/4− at 0.2V and NiFe-PBA at 0.5 V. SiO2-COOH@MIPs that could specifically recognize CAP were synthesized via thermal polymerization using carboxylated silica microspheres (SiO2-COOH) as carriers. When the CAP was adsorbed by SiO2-COOH@MIPs, the above two oxidation peak currents decreased at the same time, allowing the double-signal analysis. The SiO2-COOH@MIPs/SnS2/NiFe-PBA/GCE sensor used for determining CAP was successfully prepared. The sensor utilized the interactions of various nanomaterials to achieve high-sensitivity dual-signal detection, which had certain innovative significance. At the same time, the MIPs were synthesized using a surface molecular imprinting technology, which could omit the time of polymerization and elution and met the requirements for rapid detection. After optimizing the experimental conditions, the detection range of the sensor was 10−8 g/L–10−2 g/L and the limit of detection reached 3.3 × 10−9 g/L (S/N = 3). The sensor had satisfactory specificity, reproducibility, and stability, and was successfully applied to the detection of real milk samples.

In this report, for the first time, we have applied green synthesized NiFe2O4 and CoFe2O4 nanoparticles as electrode materials for supercapacitors (SCs). Bean pods extracts were used for the green synthesis of NiFe2O4 and CoFe2O4 nanoparticles. The structure and morphology of the samples were characterized by fourier transform infrared spectroscopy (FTIR), X‐ray diffraction (XRD), energy dispersive X‐ray (EDX), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). From XRD analysis, it was determined that NiFe2O4 and CoFe2O4 nanoparticles had a crystalline structure. EDX analysis confirms the presence of carbon and the stoichiometries of NiFe2O4 and CoFe2O4. In TEM analyses, it was determined that the sizes of nanoparticles varied in the range of 5–20 nm. The FTIR spectra supported the presence of Fe−O, Ni−O, and Co−O bonds. Electrochemical measurements of active materials were performed using cyclic voltammetry, galvanostatic charge‐discharge, and electrochemical impedance spectroscopy techniques in a 1 M H2SO4 solution. It was determined that the specific capacitance value of NiFe2O4 (129 F/g) was higher than that of CoFe2O4 (106 F/g). The cyclic stability of CoFe2O4 and NiFe2O4 was found to be 59 and 106 % retention at the end of 10000 cycles, respectively. The specific capacitance value and very good cyclic stability of NiFe2O4 showed that it is a good active substance that can be used in supercapacitor applications.
