Interfacially coupled thin sheet-like NiO/NiMoO₄ nanocomposites synthesized by a simple reflux method for excellent electrochemical performance

Abstract

Herein, hierarchical sheet-like assemblies of interfacially coupled NiO/NiMoO4 (NNMO) nanocomposites are prepared by simple and cost-effective one-step aqueous reflux method followed by post-thermal treatment. Reaction time is optimized for high...

Mesoporous NiMoO4 nanorod electrode materials for flexible and asymmetric energy storage devices

“…[14][15][16][17] Compared to binary transition metal oxides, the ternary NiMoO 4 compound shows richer oxidation states because of the synergistic effect of bimetallic interactions. [18][19][20] It results in highly reversible redox reactions and excellent electrochemical performance. 21,22 In previous reports, Wang et al prepared Pr 2 CrMnO 6 electrode materials with a specic capacitance of 177.4 F g −1 at 2 A g −1 .…”

Mesoporous β-Ag2MoO4 nanopotatoes as supercapacitor electrodes

“…10,14 Additionally, these AxMoOy have good ionic conductivity with regard to the electrolyte ions, which is responsible for the substantially high specific capacity and energy density because the conductive channels are paved with metal or transition metal ions. 4,7 Motivated by these qualities, various transition metal molybdates, including NiMoO4, 15,16 CoMoO4, 2,17,18…”
