Abstract: the competition between the precipitation of cobalt ions and evolution of hydrogen gas on the cathode surface duringthe reduction process in a sulfate bath, investigation on the mechanism of metal precipitation is of great importance.In the present work, study on the kinetics of cobalt electrowinning and the mechanism of the involved reactions havebeen carried out. The obtained result...
Sulfonamides are an important class of synthetic antibacterial medications that is widely utilized and pollute many water bodies. In this study, sulfamethoxazole was selected as the representative sulfa antibiotics. A molybdenum disulfide-based catalyst synthesized by hydrothermal method used to activate peroxymonosulfate (PMS) for degradation in water. Co@MoS 2 characterized scanning electron ...
Composite materials: Tungsten disulfide and WS2 /reduced graphene oxide (WS2 /rGO) nanosheets were fabricated by hydrothermal synthesis using tungsten chloride, thioacetamide, and graphene oxide (GO) as starting materials. The WS2 nanosheets are efficiently templated on the rGO layer. The WS2 /rGO hybrid nanosheets show much better electrocatalytic activity for the hydrogen evolution reaction t...
.Herein, we report the synthesis of tungsten based nanostructures such as WO 3 , 3− x (WO 2.72 : WS 2 ), and through a facile single step hydrothermal technique evaluated their supercapacitor performance for energy storage applications.
Background and Objective: Arsenic has long been considered as a heavy metal and toxic pollutant due to its potential to harm the human health and the environment. Adsorption is one of the mechanisms for arsenic removal from wastewater. Therefore, the purpose of this research was to investigate the feasibility of synthesized chitosan-zirconium magnetic nano fiber on arsenic adsorption from wast...
Controllable synthesis of various ZnO nanocrystals was achieved via a simple and cost-effective hydrothermal process. The morphology evolution of the ZnO nanostructures was well monitored by tuning hydrothermal growth parameters, such as solution concentration, reaction temperature, and surfactant. As-obtained ZnO nanocrystals with different morphologies, e.g., ZnO nanorods, nanotetrapods, nano...
Composite nanostructures of coral reefs like p-type NiO/n-type ZnO were synthesized on fluorine-doped tin oxide glass substrates by hydrothermal growth. Structural characterization was performed by field emission scanning electron microscopy, high-resolution transmission electron microscopy, and X-ray diffraction techniques. This investigation shows that the adopted synthesis leads to high crys...
In this research we first synthesized MgFe2O4 nanostructures via hydrothermal method using (Mg(NO₃)₂.6H₂O) and (Fe(NO₃)₃.9H₂O). The influence of concentration, surfactant, precipitating agent and temperature on the particle size and magnetic properties of the synthesised nanoparticles were examined. Then MgFe2O4-Ag nanocomposites were prepared by a simple chemical precipitation. The structural ...
