Multiwalled Carbon Nanotubes beaded with Nickel Molybdate for superior electrochemical characteristics

Abstract

NiMoO4 were synthesised on multiwalled carbon nanotubes (MWCNTs) via a simple and environment-friendly solvothermal method. The nanostructures were interconnected forming a sponge-like network providing a large surface area easily accessible to electrons and ion during intercalation-deintercalation process. The MWCNT/NiMoO 4 nanocomposite exhibited a specific capacitance of 455 F/g at 4 A/g as an electrode material for an electrochemical capacitor and 66 % of its initial capacitance was retained after 1000 cycle. This study presented a research strategy for developing ternary based electrode material for electrochemical capacitors.
