The Sabatier Principle in Electrocatalysis: Basics, Limitations, and Extensions

“…Section "Validity of the BEP Relationship") (Exner, 2019d(Exner, , 2020c. In addition to these and many other studies based on microkinetic considerations in the steady-state approximation (Wang et al, 2009;Holewinski and Linic, 2012;Marshall and Vaisson-Béthune, 2015;Shinagawa et al, 2015;Tao et al, 2019;Mefford et al, 2020;Tichter et al, 2020;, Dauenhauer and coworkers directly calculated the timedependent kinetics of electrochemical processes, proposing that an oscillation in the driving force may lead to an enhancement in the reaction rate compared to the steady state (Ardagh et al, 2019;Shetty et al, 2020). This is because temporal oscillations allow a single catalytic material to exhibit multiple free-energy landscapes, which promote different parts of the reaction.…”

A vertically paired electrode for redox cycling and its application to immunoassays

“…The k app value represents the electron transfer rate constant for the redox reaction of the following equation: d[Fe(CN) 6 4− ]/d t = k app ·[Fe(CN) 6 3− ]. 26 The k app value for the PEDOT:PSS electrode was determined according to the Nicholson method, as shown in Fig. S1(b) †…”

Electrochemical and spectroscopic study of vanadyl acetylacetonate–ionic liquids interactions

“…This indicates a kinetic limitation, the rate of the half-reaction being still limited by the slow kinetics at the electrode surface, even if mass transport were infinite (i.e., infinite rotation rate). Hence, with the addition of ILs 3, 4, 5, and 6, the redox reaction was in turn limited by sluggish kinetics rather than by mass transport [41] .…”
