Controlled Synthesis of Nickel Doped Molybdenum Oxide for High Performance Supercapacitors

Abstract

NiMoO4 nanocomposite for supercapacitors have successfully developed via hydrothermal method at 120oC for different time (6h, 7h, 21h) for making 3 samples. Synthesized materials is suitable for psuedocapacitors because it sores charge via redox reactions during charging and discharging. Nickel doped molybdenum oxide materials in composite form has been used for super capacitors analysis in order to take the benefit of high-performance stability and capacitance. Electrochemical properties were investigated by using KOH as an electrolyte solution. FTIR shows the flexing, stretching, and antisymmetric bonding present in nanocomposite between molybdenum and nickel. NiMoO4 heat treated at 21 hours considered best due to less charge and discharge cycle time determined by GCD. Hight specific capacitance shows the better performance of prepared NiMoO4 that treated for 21 hours. CV shows the material have pseudocapacitive behavior and large potential window belong NiMoO4 with higher current range which makes it functional.
