The present study involves the synthesis of a bismuth oxide (Bi2O3) electrode consisting an arranged nano-platelets for evolving flower-type surface appearance on nickel-foam (Bi2O3-Ni-F) by simple, inexpensive, binder-free and one-step chemical bath deposition (CBD) method, popularly known as wet method. as-prepared Bi2O3 Ni-foam, material, demonstrates 557 F g-1 specific capacitance (SC, at 1 mA cm-2), which 85% is retained even after 2000 cycles. With power density 500 kW kg-1, Bi2O3-Ni-F...
Superfast (≤10 min) room-temperature (300 K) chemical synthesis of three-dimensional (3-D) polycrystalline and mesoporous bismuth(III) oxide (Bi2O3) nanostructured negatrode (as an abbreviation negative electrode) materials, viz., coconut shell, marigold, honey nest cross section rose with different surface areas, charge transfer resistances, electrochemical performances essential for energy storage, harvesting, even catalysis devices, are directly grown onto Ni foam without poly(ethylene...

Soft chemical synthesis is used to obtain a hydrangea-type bismuth molybdate (Bi2MoO6) supercapattery electrode that demonstrates considerable energy/power density and cycling life. Structure morphology studies, initially, reveal phase-pure polycrystalline surface appearance for Bi2MoO6, which upon testing in an electrochemical energy storage system displays behavior, combination of supercapacitor battery. From the power law, applied-potential-dependent charge mechanism established Bi2MoO6...

Sulphur source-inspired self-grown polycrystalline and mesoporous nickel sulfide (Ni xS y) superstructures with vertically aligned nanomorphologies viz. rods, flakes, buds, petals, synthesized at elevated temperatures moderate pressures by a facile one-pot hydrothermal method on three-dimensional Ni foam demonstrate remarkable areal specific capacitances of 7152, 4835, 2160 F cm-2 current densities 1, 2, 5 mA cm-2, respectively, cycling stability 94% for battery-type electrochemical...
In this work, we report the synthesis of a Bi2O3-MnO2 nanocomposite as an electrochemical supercapacitor (ES) electrode via simple, low-cost, eco-friendly, and low-temperature solid-state chemical process followed by air annealing. This as-synthesized was initially examined in terms its structure, morphology, phase purity, surface area using different analytical techniques thereafter subjected to measurements. Its performance demonstrated excellent supercapacitive properties wide potential...
The creation of hydrogen and oxygen from water can be a paramount way to produce clean fuel through Earth-abundant non-precious photoelectrochemical (solar production) electrocatalysis processes. Since two decades, nickel (Ni)-based electrocatalysts are being extensively applied as bifunctional electrocatalysts. Here, recent advances Ni-based catalysts in electrochemistry for splitting application evolution reaction (OER) (HER) processes with evaluation parameters like dependency the current...
