Homogeneous mediators of free metal ions such as Ag(II), Ce(IV), and Co(III) are highly energetic for complete oxidation of environmental pollutants. At the same time, low valent free metal ions have the tendency for reduction of pollutants but their stability restricts to use further. Among many ways to stabilize the low valent metal ions, electrolyte concentration variation itself act as a stabilizer in many situations. Here, cyclic voltammetry studies planned to investigate the Co(OH)2 and Cu(OH)2 redox behavior. From the redox behavior, one can say whether the low valency of metal ions stabilized. In first the stage, solubility of Co(OH)2 and Cu(OH)2 analyzed using different concentrations of KOH. The same concentrations of KOH planned to used CV analysis in different scan rates. From the CV peak potential and current variation results, one can derive whether the process follows diffusion controlled. To support the cyclic voltammetry results, SEM and XRD analyses of the electrodes adopted. Finally, there will be a discussion on stabilization of Co(OH)2 and Cu(OH)2 upon reduction. |
