| 摘 要： | 银离子交换沸石Y修饰电极(Ag+-沸石Y)的循环伏安(CV)行为, 不同于溶液中的银离子在固体银电极表面上的CV行为. Ag+-沸石电极中银离子还原电位明显受沸石体内银簇影响. 依据Ag+-沸石修饰电极在含有能够与银离子形成难溶盐的电解质中的CV行为, 本文发现了沸石对溶液中阴离子具有尺寸选择效应, 并解释了银离子交换沸石修饰电极的循环伏安反应特性.

| Abstract: | The cyclic voltammegrams(CV)of silver ions exchanged zeolite modified electrode(Ag + zeolite)differed from the behavior of silver ions from an aqueous solution on solid sliver electrode.The formation of silver clusters in the pores of zeolite had a significant effect on the CV behavior of electrodes.In light of CV characteristics of Ag + zeolite electrodes in the electrolyte solution containing anions forming insoluble salt with Ag +,a selectivity of Ag + zeolite for anions was proposed to explain CV characteristics of Ag + zeolite Y. |
