An electrochemical quartz crystal microbalance study into the deposition of manganese dioxide
چکیده انگلیسی

An electrochemical quartz crystal microbalance (EQCM) has been used to study the effects of electrolyte composition (MnSO4 and H2SO4 concentrations) and anodic current density on the electrodeposition of manganese dioxide. The EQCM, in tandem with the electrode voltage during deposition, has been used to characterize features of the deposition mechanism such as the relative lifetime of the Mn(III) intermediate, the rate of soluble Mn(III) hydrolysis to form MnOOH, and the porosity of the resultant manganese dioxide deposit as a function of crystal nucleation. The connection between the results obtained here and commercial electrodeposition of manganese dioxide were also discussed.
