“…Magnetic nanoparticles (MNPs) consist of a magnetic material and a chemical component, and the functionality and application of MNPs are directly influenced by these two components. 213 The core of MNPs is primarily synthesized from Fe 3 O 4 and typically comprises iron oxides such as Fe 3 O 4 , hematite (α-Fe 2 O 3 ), maghemite (γ-Fe 2 O 3 ), and FeO (iron( ii ) oxide). 214 The development and implementation of efficient techniques for the synthesis of high-quality nanomaterials is crucial.…”

“…Dumitru and her co-works, where CuBi 2 O 4 particles was used toward the amoxicillin sensing, the electrode was constructed from CuBi 2 O 4 /CNF paste electrode and a comparison with the CNF paste electrode. The cyclic voltametric explorations indicate a good electroanalytical performance for AMX detection [12]. The detection and quanti cation of AMX became important nowadays, in this context we explored the electrochemical sensing of AMX using silver metavanadate, obtained via solid state method, and characterized using, X ray diffraction, Infrared spectroscopy and MEB spectroscopy.…”

The weighty industrialization, rapid urbanization and the changing lifestyle have been considered as a worldwide threat, these human activities produce a huge pollutant element especially in water such as antibiotics, heavy metals etc.. Hence, the sensing and quantification of trace pollutants in aquatic system have been becoming a necessity tool to develop. In this work, we synthesis the silver metavanadate AgVO3 through solid state reaction, the obtained powder was analyzed using X-ray diffraction, infrared spectroscopy and scanning electronic microscopy to check the structure and purity of the silver metavanadate. The elaborated compound as a modifier of carbon paste electrode to investigate the sensing of amoxicillin in aqueous solution by means of square wave voltammetry. The effect of electrochemical and chemical parameters on the current intensity was optimized. Under optimized conditions, the prepared electrode had a detection limit of 0.731µM. The interaction between amoxicillin molecule and AgVO3 surface was also investigated, which shows spontaneous adsorption process.

“…In recent years, photocatalysis, as one of the advanced oxidation processes, has provided a promising pathway for solar energy conversion [1], which reserves broad prospects of applications in wastewater treatment, air purification, solar cells, antibacterial agents and many other fields. Current exploration of the highly active photocatalyst functioning in the visible lights has attracted remarkable attention [2][3][4]. Nickel ferrite (NiFe 2 O 4 ) is one of the most interesting ferrites thanks to the dependence of its performance on particle size.…”

At present, the research focus has been aimed at the pursuit of the design and synthesis of catalysts for effective photocatalytic degradation of organic pollutants in wastewater, and further exploration of novel materials of the photodegradation catalyst. In this paper, the Sol−gel route after thermal treatment was used to produce NiFe2O4 carbon aerogel (NiFe2O4−CA) nanocomposites with cotton linter cellulose as the precursor of aerogel, by co−precipitating iron and nickel salts onto its substrate. The structure and composition of these materials were characterized by X−ray diffraction (XRD), energy dispersive spectroscopy (EDS), Raman spectra, high−resolution scanning electron microscopy (HR−SEM), high−resolution scanning electron microscope mapping (SEM−mapping), X−ray photoelectron spectroscopy (XPS) and Brunauer–Emmett–Teller (BET)’s surface area. The magnetic properties of the material were analyzed by a vibrating−sample magnetometer (VSM). Moreover, diffuse reflectance spectra (DRS), electrochemical impedance spectroscopy (EIS) and photo−luminescence spectroscopy (PL) characterized the photoelectric properties of this cellulose−aerogels−based NiFe2O4−CA. Methylene blue (MB) acted as the simulated pollutant, and the photocatalytic activity of NiFe2O4−CA nanocomposites under visible light was evaluated by adjusting H2O2 content and the pH value. The results showed that the optical absorption range of nickel ferrite was broadened by doping cellulose−aerogels−based carbon, which exerted more positive effects on photocatalytic reactions. This is because the doping of this aerogel carbon promoted a more uniform distribution of NiFe2O4 particles. Given the Methylene blue (MB) degradation reaction conformed to the first−order kinetic equation, the NiFe2O4−CA nanocomposites conducted excellent catalytic activity by maintaining almost 99% of the removal of MB (60 mg/L) within 180 min and upheld excellent stability over four consecutive cycles. This study indicated that NiFe2O4−CA nanocomposites reserved the potential as a future effective treatment of dye wastewater.
