Influence of particle size distribution on insertion processes in composite electrodes. Potential step and EIS theory

Autor: B. Le Gorrec, Jean-Paul Diard, Claude Montella

Publikováno v: Journal of Electroanalytical Chemistry. 499:67-77

Diffusion of guest species in particles of host material in composite electrodes is investigated for potential step and EIS methods taking particle size distribution into consideration. Theoretical expressions are derived for the output response to a

Linear diffusion impedance. General expression and applications

Autor: Jean-Paul Diard, Claude Montella, B. Le Gorrec

Publikováno v: Journal of Electroanalytical Chemistry. 471:126-131

Linear diffusion in thin film electrodes can be interpreted in terms of a matrix relationship. A general expression for the mass-transfer function and the diffusion impedance can be written, irrespective of the boundary conditions at the film surface

Discontinuous immittance due to a saddle node bifurcation

Autor: B. Le Gorrec, Jean-Paul Diard, Claude Montella, Fabienne Berthier

Publikováno v: Journal of Electroanalytical Chemistry. 458:231-240

The Frumkin isotherm for the electrosorption reaction is S-shaped for the interaction parameter values lower than a critical level, leading to a hysteresis loop during steady-state studies. It is shown that isotherm branch switching phenomena can occ

Copper electrodissolution in 1M HCl at low current densities. II. Electrochemical impedance spectroscopy study

Autor: J.-M. Le Canut, B. Le Gorrec, Jean-Paul Diard, Claude Montella

Publikováno v: Electrochimica Acta. 43:2485-2501

Anodic oxidation of a copper rotating disk in 1 M HCl is studied by electrochemical impedance spectroscopy (EIS). Experimental impedance diagrams show two capacitive loops separated in frequency. These diagrams validated with Kramers–Kronig relatio
