摘要:  应用循环伏安法于铂电极上电化学沉积PB膜,并由电化学石英晶体微天平技术(EQCM)原位测量了PB膜电沉积过程的频率响应.研究表明,沉积液中添加邻菲咯啉对PB膜结构有影响.有邻菲咯啉参与沉积的PB Pt/QCM电极对H2O2的电催化还原性能优于不含邻菲咯啉沉积液制备的PB Pt/QCM电极.

Abstract: Prussian blue (PB) films were electrodeposited on the Pt/QCMelectrodes in the solutions with or without Phenanthroline by cyclic voltammetry. The frequencyshift during electrodeposition wasmeasured,and the EQCM behaviors of these two types of PB films in potassium chloridewere also studied. Results show that electrodeposition process of PB film in the solution with phenanthroline wasdifferent from that in the solution without phenanthroline. The PB film modified Pt/QCMelectrodeprepared in the solution with phenanthroline shown an excellent electrocatalytic activity for the reduction process of hydrogen peroxide.

Key words: Prussianbluefilm, Phenanthroline, EQCM(Electrochemical Quartz Crystal Microbalance), Cyclic Voltammetry, Electrocatalysis, Hydrogen peroxide
