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.
