Theoretical-experimental synergy towards better understanding of interfacial electron transfer kinetics

Important questions at the molecular level of electrode kinetics remain open or controversial. This situation reflects the complexity of heterogeneous electron transfer events, as affected by classical and quantum factors of different nature that interplay along a region of highly spatially-dependent properties. Consequently, cumbersome, multi-parametric ki-netic models arise, which are not always easily or accurately considered in experimental works, missing the chance of getting molecular insights and simultaneously assess the model assumptions. This calls for a joint theoretic-experimental effort for accessible theoretical tools, experi-mental protocols and data analysis procedures. Some recent advances and future perspectives in these aspects are here overviewed.

Automated summary

Important questions in molecular electrode kinetics remain controversial, highlighting the complexity and spatial dependence of electron transfer events. A joint theoretic-experimental effort is needed to develop accessible theoretical tools, experimental protocols, and data analysis procedures.
