[交流] [请教]inner-sphere electron transfer 和 outer-sphere electron transfer 的区别

[请教]inner-sphere electron transfer 和 outer-sphere electron transfer 的区别


如题
哪位虫子帮忙解释一下啊
比如说电化学中常用的两种探针分子
铁氰化钾和六氨合钌
好像两个在参与反应的时候电子转移方式不同

哪位虫子了解帮忙解答一下!
谢谢!

It is conventional to classify electrochemical reactions as outer-sphere and innersphere.The former involve the outer coordination sphere of a reacting ion. Thus, little if any change inside the ion solvate shell occurs; they proceed without breakingup intramolecular bonds. But in the latter, involving the inner coordination sphere, electron transfer is accompanied by breaking up or formation of such bonds. Often the inner-sphere reactions are complicated by adsorption of reactants and/or reaction products on the electrode surface. The electron transfer in the Fe(CN)63-/4- system is example of an outer-sphere reaction (with due reservation for some complications caused by O-containing groups on the carbon electrode surface [89]). The oxidation or reduction of water molecules with O2 or H2 evolution, respectively, exemplifies inner-sphere reactions.
