abstract = {Physical modelling helps to acquire fundamental insights
from experimental data when electrochemical impedance
spectroscopy is employed for mechanistic understandings of
electrocatalytic reactions. Herein, we report an analytical
solution for chemisorption impedance from a consistent
treatment of ion transport in the solution and electron
transfer on the surface. Our formulation avoids both a
priori decoupling of double-layer charging and electron
transfer reaction, and a strict separation of double-layer
charging and ion transport. Ion transport in the entire
solution region is described by the Poisson-Nernst-Planck
theory and electron transfer kinetics on the electrode
surface by the Frumkin-Butler-Volmer theory. Surface dipoles
caused by partially charged chemisorbates are considered.
The classical Frumkin-Melik-Gaikazyan model for
chemisorption is retrieved as a limiting case. The obtained
formula is validated using experimental data of hydrogen
adsorption at Pt(111). Characteristic frequencies and
asymptotic behaviors of chemisorption impedance are
analyzed.},
