| Abstract: | 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. |

| Keywords: | electrochemical oscillation EQCM Hydrogen peroxide acidic solution |
