The potential distribution at the electrode interface is crucial in electrochemistry, but the classic G-C-S model is not suitable for nanosized particles collision electrochemistry. A new theoretical model called M-S-MNP is proposed to reveal the dynamic electrode potential distribution at the single-nanoparticle level, showing the influence of nanoparticles on potential distribution. Experiments and simulations show the potential roles of the M-S-MNP model in understanding the charge transfer process at the nanoscale.
The potential distribution at the electrode interface is a core factor in electrochemistry, and it is usually treated by the classic Gouy-Chapman-Stern (G-C-S) model. Yet the G-C-S model is not applicable to nanosized particles collision electrochemistry as it describes steady-state electrode potential distribution. Additionally, the effect of single nanoparticles (NPs) on potential should not be neglected because the size of a NP is comparable to that of an electrode. Herein, a theoretical model termed as Metal-Solution-Metal Nanoparticle (M-S-MNP) is proposed to reveal the dynamic electrode potential distribution at the single-nanoparticle level. An explicit equation is provided to describe the size/distance-dependent potential distribution in single NPs stochastic collision electrochemistry, showing the potential distribution is influenced by the NPs. Agreement between experiments and simulations indicates the potential roles of the M-S-MNP model in understanding the charge transfer process at the nanoscale.
