Název v původním jazyce

Silver doped NiAl2O4 nanoplates anchored onto the 2D graphitic carbon nitride sheets for high-performance supercapacitor applications

Popis výsledku v původním jazyce

In the current study, NiAl2O4, and silver doped NiAl2O4 were synthesized via a sol-gel approach and their composite with g-C3N4 was successfully prepared via an ultrasonication approach. The char-acterization of as fabricated materials was carried out via various conventional techniques. Furthermore, the electrochemical behavior of the as-fabricated electrode materials was investigated via various electrochemical techniques. The results of electrochemical measurements were analyzed for all three prepared electrodes and Ag-NiAl2O4@g-C3N4 nanocomposite was found to be a more active electrode material than other prepared electrodes. Ag-NiAl2O4 @g-C3N4 showed specific capacitance of 768 Fg-1, 94.01% capacitance retention after 6000 CV cycles, 519 s discharge time, 0.51 ohm charge transfer resistance, 27 WhKg-1, and 187.28 WKg-1 energy and power densities respectively. Ag-NiAl2O4@g-C3N4 can be considered a potential and propitious electrode material for high-performance supercapacitors.(c) 2022 Elsevier B.V. All rights reserved.
