我们报道了在298 K低过电位区铂电极上电位诱导的二氧转化过程中质子转移（PT）中的量子隧道效应的观察。然而，这个量子过程在高区域被转换成经典的PT格式。因此，PT （QCT-PT）过程作为势的函数存在量子到经典的跃迁，理论分析证实了这一点。这一观察结果表明，在低条件下，量子隧穿控制着双氧的多步电子-质子驱动转变。
We report an observation of a quantum tunneling effect in a proton-transfer (PT) during potential-induced transformation of dioxygen on a platinum electrode in a low overpotential () region at 298 K. However, this quantum process is converted to the classical PT scheme in the highregion. Therefore, there is a quantum-to-classical transition of the PT (QCT-PT) process as a function of the potential, which is confirmed by theoretical analysis. This observation indicates that the quantum tunneling governs the multistep electron-proton-driven transformation of dioxygen in the lowcondition.
