The Bragg reflections confirms the formation of cubic spinel structure and also the absence of other impurities. The crystallite size estimated from Scherrer’s method found to decrease from 14.11 to 5.37 nm with increase in dopant concentration. The surface morphology consists irregular shaped agglomerated Nps.

The cyclic voltametry analysis were also carried out to know the redox reactions, electrode kinetics, and electrochemical behavior.
