摘要
将磷钼杂多酸聚吡咯(PMo12-PPY)用电聚合法沉积在载有多孔阳极氧化铝(AAO)的玻碳电极表面(AGCE),制备了PMo12-PPY/AGCE纳米复合材料修饰电极,并通过循环伏安(CVs)、电化学阻抗谱(EIS)方法表征了PMo-PPY/AGCE和PMo-PPY/GCE的电化学性质及电极界面反应特征.结果表明,AAO膜使电极表面粗糙度降低,电子传输的能力增强,并使氧化还原反应速度加快.
The PMO12-PPY/AGCE nanocomposite modified electrode prepared by electrodeposition of Polyoxometalates - polypyrrole(PMo12-PPY)on the glass carbon electrode covered with a macroporous alumina membrane(AAO). Electrochemical property and electrode interface reaction characteristics of PMo-PPY/AGCE and PMo-PPY/GCE were analysed with the cyclic voltammograms(CVs) and elec- trochemical impedance (EIS). The results indicated that macroporous AAO membrane can reduce roughness of modified electrode surface, enhance the ability of electronic transmission and accelerate the speed of redox reaction.
