金属化聚邻甲苯胺膜修饰电极的性能研究
, PP. 161-166
Keywords: 聚邻甲苯胺,Pt电沉积,异丙醇电氧化,化学修饰电极
Abstract:
在聚邻甲苯胺(POT)膜修饰电极上用电化学法沉积Pt微粒,由SEM与XRD表征其表面形态与晶面取向,同时研究异丙醇在金属化POT膜电极上的氧化行为.结果表明,Pt在POT膜上的沉积呈现晶面择优取向的现象,况且POT质子掺杂后,由于电化学活性增强,影响了沉积铂微粒的尺寸和粒径分布.异丙醇的电氧化可发生在POT的电化学活性区,当电位大于0.70V(SCE)时,POT不再呈氧化还原活性,异丙醇的电氧化主要在铂微粒上进行.聚合物不仅作为铂微粒的载体而且自身参加反应,这种微异相催化体系需用新的模型描述
