Abstract
Nanostructured molybdenum oxide having a
particle size in the range of 30–80 nm was prepared by
potentiodynamic electrodeposition method, and the effects of
H2SO4 concentration on its capacitive behavior were studied
by cyclic voltammetry, galvanostatic discharge, and electrochemical impedance spectroscopy. Poor to fair capacitive
behaviors were witnessed depending on the electrolyte
concentration and conditions of charge/discharge. Increasing
acid concentration to 0.02 M had favorable effect, while
beyond that, the effect was detrimental. Capacitance around
600 F g−1 was recorded in the potential range of 0 to
−0.55 V vs. Ag/AgCl.
