Electrochemical behaviour of ZnO–AC based nanocomposite electrode for supercapacitor

Organic template-assisted green synthesis of CoMoO4 nanomaterials for the investigation of energy storage properties

“…56 The phytofabricated CoMoO 4 exhibited an enhanced energy storage potential in comparison with several reported devices. 39,40,49,56,[65][66][67][68][69][70] On the other hand, the maximum recorded power density of CoMoO 4 was 7272.5 W kg À1 (7.3 kW kg À1 ), which is much higher than the power densities of MoO 3 , 66,70 Co 3 O 4 nanorods, 57 CoO/Co 3 O 4 , 49 CoO nanobers 56 and Co 3 O 4 @Carbon, 56 respectively. The Ragone plot (Fig.…”

Facile ZnO-based nanomaterial and its fabrication as a supercapacitor electrode: synthesis, characterization and electrochemical studies

“…2a reflects M–C, and M–O (M = Zn and Pd) bonds within frequency 600–400 cm −1 . 39,54 Thus, aromatics and 1° and 2° amines behaved as SAs in the as-prepared product.…”

“…This is again credited to the fast Faradaic reactions of PdO/Pd. [55][56][57][58][59][60][61][62][63][64][65][66][67] ED of PFbinded ZnO@PdO/Pd was also improved than ZnO-activated carbon 39 ZnO NPs. 40 Excellent PD of ZnO@PdO/Pd was 3718 W kg À1 (3.7 KW kg À1 ) (Fig.…”

“…However, CP showed a decline in CD showing a shi to low potentials. These results were in agreement with those obtained by Khan et al, 32 Duraisamy et al 34 and Pramanik et al 35 Reasons behind these ndings were kinetic irreversibility as well as electric polarization given by ions of electrolyte at the surface of the electrode with higher SR. 33,[36][37][38][39][40] This changed the CV curves shape to a rectangular form with more SR. SC values shown by the ZnO@PdO/Pd electrode are noted at different SR (Fig. 8c).…”

“…31,32 Further peaks present at 506.95, 488.86, 485.04, 433.85, and 402.97 cm À1 are demonstrating MOs of Zn31,32 Ni 33 along with Pd 34. Figure 2B gave GCMS analysis of acquired product giving peaks in compliance with Octodrine (C 8 H 19 N), cyclo-butanol (C 4 H 8 O) as part of NiO-PdO-Pd doped ZnO.…”
