Pr eparation and elect rochemica l capacitive behaviors of nan ostructured molybdenum oxide

Molyb denum oxid e is a wide band gap n-type semiconductor which plays an important role in techno logical applications bec ause of its structural and electronic properties. Due to its crystal struct ure, molybdenum oxide has widely used as ca thode materials for lithium ion batteries. Since of different oxidation numbers of molybdenu m, this is expectable that molybdenum oxide be a good candidate for pseudocapa citor, an ele ctronic device which h as a higher p ower density and long cycle life compared to batteries a nd a higher energy density compared to conventional capa citors. Seve ral method s have been developed for preparin g nanostruc tured molybdenum oxide. In this st udy, we use d potentiody namic electrodepositio n, a facile method which has several advantages like the low cost and g ood sticking of deposited materials to the current collector and investigated the pH and e lectrolyte composition effects o n the pseudocapacitive behavior of nanostructured molybde num oxide [۱-۳].
