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.

阳离子对碱性氧还原反应的影响


在最近一期的 ACS Energy Letters 中，Resasco 和他的同事研究了不同的碱金属阳离子如何影响一系列金属催化剂上的氧还原反应 （ORR）。他们得出结论，当金属催化剂的总电荷为零的电位为 ORR 电位窗口的正时，金属催化剂表现出阳离子依赖性的 ORR 速率。通过考虑界面处的阳离子如何影响速率确定步骤，可以合理化这种阳离子效应。
