The first report of deep eutectic solvents (DESs) was released in 2003 and was identified as a new member of ionic liquid (IL), involving innovative chemical and physical characteristics. Using green solvent technology concerning economical, practical, and environmental aspects, DESs open the window for sustainable development of nanomaterial fabrication. The DESs assist in different fabrication processes and design nanostructures with specific morphology and properties by tunable reaction conditions. Using DESs in synthesis reactions can reduce the required high temperature and pressure conditions for decreasing energy consumption and the risk of environmental contamination. This review paper provides the recent applications and advances in the design strategy of DESs for the green synthesis of nanomaterials. The strategy and application of DESs in wet-chemical processes, nanosize reticular material fabrication, electrodeposition/electrochemical synthesis of nanostructures, electroless deposition, DESs based nano-catalytic and nanofluidic systems are discussed and highlighted in this review.

In the present study, ZnMnFeO4 and CoMnFeO4 tri-metallic spinel oxide nanoparticles (NPs) were provided using hydrothermal methods. The nanoparticles have been characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), Fourier transform infrared spectroscopy (FTIR), energy-dispersive X-ray spectroscopy (EDX), transmission electron microscopy (TEM) and electrochemical techniques. A reliable and reproducible electrochemical sensor based on ZnMnFeO4/CoMnFeO4/FTO was fabricated for rapid detection and highly sensitive determination of hydrazine by differential pulse voltammetry. It is observed the modified electrode causes a sharp growth in the oxidation peak current and a decrease in the potential for oxidation contrary to the bare electrode. The cyclic voltammetry technique showed, there is high electrocatalytic activity and excellent sensitivity in the suggested sensor for hydrazine oxidation. Under the optimal experimental conditions differential pulse voltammetry method was used for constructing the calibration curve and a linear range of 1.23 × 10− 6 M to 0.18 × 10− 3 M with a limit of detection 0.82 ± 0.09 µM was obtained. The obtained results indicate that ZnMnFeO4/CoMnFeO4/FTO nano-sensor bears pleasant stability, reproducibility, and repeatability in hydrazine measurements. In addition, the suggested sensor was employed efficiently to ascertain the hydrazine in diverse samples of cigarette tobacco.

“…The depletion of fossil fuel reserves has created challenges like rising fuel costs, increased environmental pollution, environmental concerns, and unpredictable climate changes . To address these issues and meet the demands of intermittent energy sources like hydro, wind, solar, and tidal power, it is crucial to develop efficient, affordable, and environmentally sustainable energy storage technologies. − Supercapacitors (SCs) have arisen as a leading choice in the quest for clean and efficient energy storage solutions, primarily owing to their extraordinary ultrahigh power densities, extended cycling lifespans, cost-efficiency, and environmentally sustainable characteristics. − Nevertheless, compared to lithium-ion batteries (LIBs), the energy-storing capacity of SCs is relatively lower due to the surface-controlled electrochemical reactions, which impede the bulk utilization of the electroactive material. Hybrid supercapacitors (HSCs), which integrate a positive electrode dominated by redox processes and a carbon-based negative electrode, offer potential solutions for overcoming energy density limitations while preserving the power density and cycle life.…”

Battery-type materials with ultrahigh energy density show great potential for hybrid supercapacitors (HSCs). In this work, we have developed a nickel selenide (NiSe)/reduced graphene oxide (rGO)/graphitic carbon nitride (g-C 3 N 4 ) ternary composite as a promising positive electrode for hybrid supercapacitors (HSCs). The extended π-conjugated planar layers of g-C 3 N 4 promote strong interconnectivity with rGO, which further enhances surface area, surface free energy, and efficient electron/ ionic path. Additionally, it establishes clear ion diffusion pathways, serving as ion reservoirs during charge and discharge and facilitating efficient redox reactions. As a result, the NiSe/g-C 3 N 4 /rGO nanocomposite electrode displayed a specific capacity of 412.6 mA h g −1 at 1 A g −1 . Later, the HSC device was assembled using the nanocomposite as the positive electrode and activated carbon as the negative electrode, which delivered an energy density of 65.2 Wh kg −1 at a power density of 750 W kg −1 . Notably, the HSC device maintained excellent cyclic stability, preserving 93.3% of its initial performance and Coulombic efficiency of 86.6% for 10,000 charge−discharge cycles at 5 A g −1 . These findings underscore the potential utility of NiSe/g-C 3 N 4 /rGO as a versatile and effective electrode material for the strategic development of HSC devices.
