摘　　要：制备了两组 Nafion膜气体扩散电极 (膜中分别分布有带正、负电荷的钴大环配离子 )。用稳态极化曲线比较了两种不同催化剂—四 -三甲基苯胺基卟啉钴 ( Co TMAP)和四磺基酞菁钴 ( Co T-SPc)对氧还原的催化活性。探讨了配离子和The electrocatalytic reduction of dioxygen on the gas diffusion electrode of nafion modified by macrocyclic complexes of cobalt were studied systematically by stable polarization curves. The effects of electrostatic interaction between the complex coating and Nafion film on electrocatalytic reduction of dioxygen in the presence of Co(TMAP) and CoTSPc catalysts are discussed.
