EQCM技术对电化学振荡机理的探索

An Electrochemical Quartz Crystal Microbalance Study on the Mechanism of Electrochemical Oscillation

利用石英晶体微天平技术对 H2 O2 在硫酸、高氯酸和盐酸等酸性介质中铂电极上还原反应产生的电化学振荡行为进行了较为系统的研究 ,得到了对应于 H2 O2 还原过程中两类不同电流振荡的频率响应曲线 ,讨论了可能的电化学振荡机制 .

Electrochemical oscillations, which occurred on the platinum electrode in the acidic aqueous solution (such as H 2SO 4, HClO 4 and HCl) containing hydrogen peroxide and were studied with electrochemical quartz crystal microbalance(EQCM). The frequency response curves corresponding to two types of electrochemical oscillations during the linear scanning were invistigated. The mechanism is also discussed.
