“…The electrochemical performance of Pt nanoparticles is touched by particle size, morphology and utilized substrate. The oxygen containing groups such as NiO can remove adsorbed intermediates and improve antipoisoning property . This effect is understood by comparison between the electrochemical performance of Pt/NF and Pt/NiO−GO/NF through CV studies as well as CA studies.…”

In this project, Pt/NiO−GO nanocatalyst is grown on nickel foam (NF) and, its catalytic activity towards electrochemical oxidation of methanol in acidic media is studied. The first step is devoted to the synthesis of NiO−GO support by a hydrothermal method. Then Pt nanoparticles (∼34.3 nm) are electrodeposited on this supporting material. Hydrothermal and electrochemical deposition conditions are optimized. Surface of modified NF was inspected for physical characterization and Chemical composition by some techniques such as field emission scanning electron microscopy (FESEM), energy‐dispersive X‐ray spectra (EDS), and X‐ray diffraction (XRD). In the electrochemical section, the catalytic performance of Pt/NiO−GO/NF towards methanol oxidation is investigated by cyclic voltammetry and chronoamperometry measurements. The electrochemical impedance spectroscopy (EIS) is elected to deliberate charge transfer resistance on the catalyst surface. Mass activity, electrochemical surface area (ECSA) and durability of prepared catalysts are compared with commercial Pt/C. Deliberations prove the superiority of Pt/NiO−GO/NF towards methanol oxidation in acidic media. The Superior quality of synthesized nanocatalyst that is attributed to the synergetic effect of the NiO−GO support material and Pt nanoparticles, indicate that Pt/NiO−GO/NF can be successfully used as the anode in the direct methanol fuel cell (DMFC).

“…Electrodeposition is a unique and well‐established process for the development of thin films, as it can control the surface morphology, thickness, uniformity, and is suitable for large‐area manufacturing with low capital investment [25,26] . Different types of current collectors/substrates have been used for the fabrication of electrode materials for supercapacitors such as ITO, Cu foil, Ni foil, Ni foam, carbon cloth, carbon paper etc [20,27–31] . However, the deposited metal oxides being poorly conductive and not meeting the commercial stability requirements further research is being focused on improving the electrochemical performance, stability and conductivity of the electrode materials.…”

Nanostructured transition metal oxide synthesis possessing high energy density and stability is desirable for supercapacitors. Herein, we synthesize three‐dimensional NiCo2O4 (NCO) nanosheets with oxygen vacancies induced by sustainable and environmentally benign electrodeposition assisted chemical reduction process. Oxygen vacancies increase the conductivity, adsorptivity, and the active surface area, thereby enhancing the charge storage capabilities. The binder‐free NCO delivers the highest specific capacitance (Csp) of 2065 F g−1 at 1 A g−1, retaining 89.30 % of its initial value at 10 A g−1 after 10,000 continuous charge‐discharge (CD) cycles. An asymmetric supercapacitor (ASC) fabricated shows remarkable electrochemical properties with high energy density (Emax) of 28.6 Wh kg−1 and power density (Pmax) of 7.5 kW kg−1. The assembled ASC reports exceptional cyclic retention of 90.6 % for 10,000 CD cycles with practical demonstration. The approach used herein is suitable for eco‐friendly supercapacitor electrode fabrication with large scale manufacturing capability and less capital investment.

N-doped porous carbon encapsulated NiO/Ni composite nanomaterials (N-doped NiO/Ni@C) was successfully obtained by a one-step solution combustion method. This study demonstrates a one-step combustion method to synthesize n-doped porous carbon encapsulated NiO/Ni composite nanomaterials, using carbon dioxide as the carbon source, nickel nitrate as the nickel source, and hydrazine hydrate as the reaction solution. Spherical NiO nanoparticles with a particle size of 20 nm were uniformly distributed in the carbon matrix. The load of NiO/Ni can be controlled by the amount of nickel nitrate. The range of carbon content of recovered samples is 69–87 at%. The content of incorporated nitrogen for recovered samples is 1.94 at%. As the anode of lithium ion battery, the composite material exhibits high capacity, excellent multiplier performance and stable circulation performance. N-doped NiO/Ni@C-2 was applied to lithium ion batteries, and its reversible capacity maximum is 980 mAh g−1 after 100 cycles at the current density of 0.1 A g−1. Its excellent electrochemical properties imply its high potential application for high-performance lithium-ion battery anode materials.
