甲基磺酸溶液中二价锡离子在玻碳电极上的初期沉积行为

Initial electrodeposition behavior of stannous ions on glassy carbon electrode in methanesulfonic acid electrolyte

采用循环伏安法和计时电流法对甲基磺酸溶液中二价锡离子在玻碳电极上的初期沉积行为进行研究,考察了二价锡离子浓度、pH、温度和添加剂对二价锡离子初期沉积行为的影响。结果表明:二价锡离子在甲基磺酸溶液中的电沉积按连续成核及受扩散影响生长的机理进行,该沉积机理不受上述因素的影响。

The initial electrodeposition behavior of stannous ions onto glassy carbon electrode in methanesulfonic acid electrolyte was studied by cyclic voltammetry and chronoamperometry.The effects of stannous ion concentration,pH,temperature,and additives on the initial deposition behavior of stannous ions were discussed.The results showed that the electrodeposition of stannous ions in methanesulfonic acid electrolyte follows the progressive nucleation and diffusion-controlled growth mechanism,which is independent of the said factors.
