Recent advances and various detection strategies of deep eutectic solvents for zinc air batteries.

Sustainable technology in energy-related applications will be crucial in the coming decades. As a result, developing new materials for existing processes has presently arisen as a major research priority. Recently, Deep eutectic solvents (DESs) have been expected as low-cost task-specific solvents for zinc-air batteries (ZABs).

Engineering of CoO electrode via Ni and Cu-doping for supercapacitor application.

Although cobalt oxides show great promise as supercapacitor electrode materials, their slow kinetics and low conductivity make them unsuitable for widespread application. We developed Ni and Cu-doped CoO nanoparticles (NPs) via a simple chemical co-precipitation method without the aid of a surfactant. The samples were analyzed for their composition, function group, band gap, structure/morphology, thermal property, surface area and electrochemical property using X-ray diffraction (XRD), ICP-OES, Fourier transform infrared (FTIR) spectroscopy, Ultraviolet-visible (UV-Vis), Scanning electron microscopy (SEM), Thermogravimetric analysis (TGA) and/or Differential thermal analysis (DTA), Brunauer-Emmett-Teller (BET), and Impedance Spectroscopy (EIS), Cyclic voltammetry (CV), respectively.

Binary glycerol-based deep eutectic solvents containing zinc nitrate hexahydrate salt for rechargeable zinc air batteries applications with enhanced properties.

Deep eutectic solvents (DESs) have attracted interest due to their unique and favorable electrochemical characteristics. This study reported a novel binary glycerol-zinc salt deep eutectic solvents were prepared with a combination of hydrogen bond donor (glycerol (Gly)) and hydrogen bond acceptor (Zinc nitrate hexahydrate (ZNH)) at different molar ratios of 1:2, 1:3, 1:4, 1:5, and 1:6. The various physicochemical properties including viscosity, refractivity index, conductivity, thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), cyclic voltammetry (CV) and electrochemical impedance (EIS) were measured.

Enhancing pseudocapacitive properties of cobalt oxide hierarchical nanostructures via iron doping.

Through co-precipitation and post-heat processing, nanostructured Fe-doped CoO nanoparticles (NPs) were developed. Using the SEM, XRD, BET, FTIR, TGA/DTA, UV-Vis, and techniques were examined. The XRD analysis presented that CoO and CoO nanoparticles that had been doped with 0.

Ag doped CoO nanoparticles for high-performance supercapacitor application.

Ag doped CoO nanoparticles (NPs) were synthesized via a co-precipitation method changing the concentration of Ag. The crystal structure, morphology, surface area, functional group, optical band gap, and thermal property were investigated by XRD, SEM, BET, FTIR, UV-Vis, and TGA/DTA techniques. The XRD results showed the formation of single-cubic CoO nanostructured materials with an average crystal size of 19.

Engineering nanostructured Ag doped α-MnO electrocatalyst for highly efficient rechargeable zinc-air batteries.

Engineering of highly active, and non-precious electrocatalysts are vital to enhance the air-electrodes of rechargeable zinc-air batteries (ZABs). We report a facile co-precipitation technique to develop Ag doped α-MnO nanoparticles (NPs) and investigate their application as cathode materials for ZABs. The electrochemical and physical characteristics of α-MnO and Ag doped α-MnO NPs were compared and examined via CP, CV, TGA/DTA, FT-IR, EIS, and XRD analysis.

The remarkable performance of a single iridium atom supported on hematite for methane activation: a density functional theory study.

Methane is the major component of natural gas, and it significantly contributes to global warming. In this study, we investigated methane activation on the α-FeO(110) surface and M/α-FeO(110) surfaces (M = Ag, Ir, Cu, or Co) using the density-functional theory (DFT) + method. Our study shows that the Ir/α-FeO(110) surface is a more effective catalyst for C-H bond activation than other catalyst surfaces.

Controlled synthesis of CdSe quantum dots by a microwave-enhanced process: a green approach for mass production.

A method that does not employ hot-injection techniques has been developed for the size-tunable synthesis of high-quality CdSe quantum dots (QDs) with zinc blende structure. In this environmentally benign synthetic route, which uses less toxic precursors, solvents, and capping ligands, CdSe QDs that absorb visible light are obtained. The size of the as-prepared CdSe QDs and thus their optical properties can be manipulated by changing the microwave reaction conditions.
