Morphology dependent electrochemical capacitor performance of NiMoO4 nanoparticles

A simple approach was adapted to synthesis nanoplatelet, nano urchin-flower and nanosphere NiMoO4 by employing cetyl trimethyl ammonium bromide (CTAB) as a capping agent. Product pseudocapacitive property was studied by measuring suitable parameters. SEM studies revealed diverse morphology of NiMoO4 nanoplatelet, nano urchin-flower and nanosphere within nanoscale region. Electrochemical studies explored the better electrode behavior of NiMoO4 nanoplatelet (RC1) with specific capacitance of 178 F/g at 10 mV/s scan rate and 110 F/g at 100 mV/s scan rate. A Nyquist spectrum of products (RC1, RC2 and RC3) also revealed the better pseudocapacitive performance of NiMoO4.
