A hydrothermal procedure was employed to synthesize hexahedron shaped MnMoO<sub>4</sub> wrapped with graphene exhibiting high energy density and power density.
Abstract Vanadium pentoxide (V 2 O 5 ) is renowned among the highly efficient supercapacitor electrode‐materials for high power and energy densities, excellent specific capacitance, prolonged cycle lives, variable oxidation states of V, reversible nature interconversions, theoretical importance, etc. Various synthetic methodologies morphologies, formation composites, doping tuning properties are additional causes interest. Different techniques like sol‐gel, solvothermal, electro‐deposition,...
Conducting flexible carbon fiber (CF) cloth was used as a substrate for the hydrothermal growth of nickel hydroxide (Ni(OH)2) and cobalt hydroxy carbonate [Co(OH)xCO3] with unique hierarchical flowery architecture then supercapacitor electrode. In three-electrode configuration in 6 M KOH aqueous electrolyte, CF-Ni(OH)2 CF-Co(OH)xCO3 electrode showed maximum specific capacitance 789 F/g 550 F/g, respectively, at 2A/g current accompanied by outstanding cycle stability retaining 99.9% 99.5%...
In this study, a simple and cost effective hydrothermal process followed by <italic>in situ</italic> oxidative polymerization has been carried out for the synthesis of CoMoO<sub>4</sub>·0.75H<sub>2</sub>O/PANI composite.
Reducing anode catalyst layer proton- and electron-transport resistances in polymer electrolyte membrane water electrolyzers is critical to improving its performance maximizing utilization at high current density. A hydrogen pump technique adapted measure the protonic conductivity of IrOx-based layers. The resistance obtained by subtracting an assembly two NRE211 membranes hot-pressed together from with IrOx intermediate layer. through-plane in-plane electronic conductivities were also...
Unique vertically aligned PANI on rGO/Ni(OH)<sub>2</sub> composite has been synthesized by a hydrothermal method exhibiting superior electrochemical behavior.
The porosity of anode polymer electrolyte membrane water electrolyzer catalyst layers (CLs) is usually low due to the use an unsupported catalyst. By adding carbon Ir ink, which then oxidized in-situ, CL can be increased from 58% 77% while number cracks decreased. electrochemical surface area (ECSA) also increases 21.5 28.3 m2/g. Cell performance improves substantially for cells with at both and high current densities. At 1.8 V, density 3.16 3.70 A/cm2 increasing content. Volcano-shaped...
Mass transport losses in proton exchange membrane water electrolysis (PEMWE) cells have gained increased focus recent years, however two-phase flow within the anode catalyst layer (ACL) has not been extensively studied. This work uses 2-D, finite element simulations with a capillary pressure based model to study ACL. The porous media are characterised using pore size distribution (PSD), allowing for impact of structural changes be analysed. results show reaction heavily influences gas...
Nitrogen-based fertilizer, primarily urea, production generates 2.1% of global CO₂ emissions through the energy-intensive Bosch-Meiser process. Electrochemical urea synthesis offers a sustainable alternative by significantly reducing greenhouse gas and...
Inkjet printing (IJP) is studied as a novel fabrication method for catalyst coated membranes (CCMs) polymer electrolyte electrolyzers. IrO2 and Pt/C inks were deposited by IJP over the membrane to fabricate anode cathode electrodes, respectively. Optical microscopy, scanning electron microscopy (SEM) energy-dispersive X-ray spectroscopy (EDX) used ex-situ surface thickness characterization of layer (CL). SEM images show CL uniform well adhered membrane. EDX even distribution ionomer in CL....
A simple single-step electrodeposition technique was followed for the three-dimensional (3D)-interconnected binary metallic manganese-cobalt sulfide nanosheets on nickel foam (MnCoS@NF). The architecture and chemical composition of as-synthesized binder-free electrodes were analyzed by field-emission scanning electron microscopy (FESEM), high-resolution transmission (HRTEM), X-ray photoelectron spectroscopy (XPS), diffraction (XRD). MnCoS@NF achieves exceptionally high specific capacitance...
Porous media transport properties, such as permeability and diffusivity, are proportional to the porosity of sample, thereby making ability quickly estimate paramount importance. A simple inexpensive setup, free hazardous chemicals, is proposed measure total thickness polymer electrolyte fuel cell (PEFC) diffusion media. The experimental setup based on Archimedes' principle. It uses a combination wetting (n-octane or IPA) non-wetting (water) fluid both solid bulk sample volumes porous media,...
