“…The width of the 1D nanobelts is measured to be approximately in the range 57-140 nm, while the length extends from ∼300 nm to 1.14 µm. Similar results were also reported by Saghi et al [35]. Usually, the important factors affecting the morphology of the crystal include the reaction temperature, van der Waals force, hydrogen bonding, crystal field interactions, electrostatic and dipolar fields [24,36].…”

Development of novel nanostructured composites is of current interest for application as electrode materials. In this regard, an attempt has been made to synthesize NiCo2O4@V2O5 nanocomposite and compare its charge storage performance with pristine NiCo2O4 nanoparticles. HR-SEM micrographs reveal a mesoporous nanobelt like morphology of the nanocomposite with a BET surface area of ~65 m2 g-1 and average mesopore size centered on ~7.55 nm. Electrochemical measurements performed on both samples anticipate capacitive behavior with quasi-reversible redox reactions. However, NiCo2O4@V2O5 is found to demonstrate strikingly high specific capacity of 194 mAh g-1 (1742 F g-1) at 1 A g-1 along with a notable capacity retention of ~90 % even after 3000 charge –discharge cycles and Coulombic efficiency >97 % at 5 A g-1. These features are much superior to the properties of pristine NiCo2O4 nanoparticles. The results obtained in this work ascertain functional robustness of NiCo2O4@V2O5 nanocomposites as electrode materials in supercapacitors.

“…W is the mass of adsorbent (g) and V is the volume of solution (L). Different conditions of adsorption were studied such as the effect of adsorbent dosage (0.3-2.5 g /L), the effect of initial concentration (10−600 mg/L), time for shaking up to 48 h, pH (2)(3)(4)(5)(6)(7)(8)(9)(10)(11), and the effect of temperature (15, 28, and 40 °C). Removal (%) was determined by the following equation:…”

“…MB causes many diseases such as mental disorders [7], vomiting, nausea, paralysis, hypertension, and methemoglobinemia [8]. It is difficult to remove MB from ecosystems due to the presence of three rings in its aromatic structure, high stability, and resistance to biodegradability [9]. Different biological and physicochemical methods for the removal of MB have been investigated including adsorption [10], coagulation, filtration, reverse osmosis [11], reduction, and oxidation [12].…”

The present study deals with the preparation of nanomagnetite (NM), potassium carrageenan (KC), and nanomagnetite/potassium carrageenan bio-composite beads (NC). Characterization of the prepared solid materials using different physicochemical techniques such as X-ray diffraction analysis (XRD), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), transmission electron microscope (TEM), energy-disperse X-ray spectroscopy (EDX), diffuse reflectance spectrophotometer (DRS), swelling ratio (SR%), N2 adsorption, pH of point of zero charges (pHPZC), and Fourier transform infrared spectroscopy (FTIR). Comparing between adsorption and photo-Fenton degradation process for methylene blue (MB) on the surface of the prepared solid materials. Nanomagnetite/potassium carrageenan bio-composite (NC) exhibited high specific surface area (406 m2/g), mesoporosity (pore radius, 3.64 nm), point of zero charge around pH6.0, and the occurrence of abundant oxygen-containing functional groups. Comparison between adsorption and photo-Fenton oxidation process for methylene blue (MB) was carried out under different application conditions. NC exhibited the maximum adsorption capacity with 374.50 mg/g at 40 °C after 24 h of shaking time while 96.9% of MB was completely degraded after 20 min of photo-Fenton process. Langmuir's adsorption model for MB onto the investigated solid materials is the best-fitted adsorption model based on the higher correlation coefficient values (0.9771–0.9999). Kinetic and thermodynamic measurements prove that adsorption follows PSO, endothermic, and spontaneous process, while photo-Fenton degradation of MB achieves PFO, nonspontaneous, and endothermic process. Photo-Fenton degradation is a fast and simple technique at a lower concentration of dye (< 40 mg/L) while at higher dye concentration, the adsorption process is preferred in the removal of that dye.

“…[27][28][29] Of the transition series, vanadium and its oxides (VOx) are one of the most fascinating and diverse catalytic systems. They find application in the synthesis of important chemicals, [30] reduction of environmental pollutants, [31,32] and more recently for neuromorphic and switching devices. [33] The reason for their rich and disparate chemistry may briefly be related to two main aspects: the many oxidation states in which V can exist (from V 2+ to V 5+ ) and the diverse coordination geometry of the oxygen ions.…”

In the search for non‐enzymatic alternatives to glucose oxidase, reliable and microchip‐compatible approaches to catalyst development are highly desirable. Herein, the electrochemical behavior of thin films of VOx deposited by molecular beam epitaxy (MBE) on glassy carbon electrodes is reported . A process of partial etching during polarization is observed. Thereafter, highly active and stable traces of VOx act as catalytic centers for glucose electrooxidation. A mechanistic description of the electrochemical process is proposed based on evidence provided by voltammetric measurements. The sensors are calibrated both with potentiometric and amperometric techniques, the former showing a wide linear range (1–10 mM), good sensitivity (14.93 ± 0.39 µA cm−2 × mM–1) and a limit of detection (0.32 m‐M). Unlike most metal oxides, it is shown that VOx on glassy carbon is capable of successfully oxidizing glucose at −0.4 V. Such a one‐of‐kind behavior can have important ramifications for energy‐efficient integrated electrochemical sensors and non‐enzymatic glucose sensing as a whole.
