摘要

在最近一期 ACS Energy Letters 期刊上，Resasco 和他的同事研究了不同碱金属阳离子如何影响一系列金属催化剂的氧还原反应 (ORR)。他们得出结论：当金属催化剂的总电荷为零的电位为 ORR 电位窗口的正值时，其 ORR 反应速率与阳离子有关。考虑到界面上的阳离子如何影响速率决定步骤，这种阳离子效应得到了合理解释。

Cation effects on the alkaline oxygen reduction reaction

In a recent issue of ACS Energy Letters, Resasco and his colleagues examine how different alkali metal cations impact the oxygen reduction reaction (ORR) over a series of metal catalysts. They conclude that a metal catalyst exhibits cation-dependent ORR rates when its potential of zero total charge is positive of the ORR potential window. Such cation effects are rationalized by considering how the cations at the interface affect the rate-determining step.
