摘要
采用循环伏安法,以铂微盘为工作电极,铂片为辅助电极,饱和甘汞电极为参比电极,研究了甲酸在含有四丁基高氯酸铵(TBAP)电解质的乙腈有机溶液中的电氧化行为,并探讨了扫描速度、底物浓度和温度等因素对甲酸电化学氧化行为的影响。结果表明该反应是受扩散控制的不可逆反应。
With acetonitrile and tetrabutyl ammoniumperchlorate(TBAP) used as solvent and supporting electrolyte,Pt micro-disk as working electrode,Pt plate as auxiliary electrode,and saturated calomel electrode as reference electrode,the electrochemical oxidation behaviors of formic acid were studied by means of cyclic voltammetry and linear sweep.The effects of scan rate,reactant concentration and temperature on electrochemical characteristics of formic acid were studied systematically.The result showed that the electrochemical oxidation process of formic acid was controlled by the mass transfer process in a liquid phase.
