EU Electrochemical methods - 4PUPMELE

Goal(s)

This module consists of 2 parts: a 28h CM/TD supported by 16h TP (4 TP sessions).
The course covers theoretical and practical electrochemistry: what parameters are measured in electrochemistry and how are they measured?
Study of electrochemical characterization methods such as Chrono-amperometry, Chrono-potentiometer, voltammetry, and electrochemical impedance applied to the study of a simple E mechanism. Extension to a complex mechanism CE, EE. 4 practical exercises put electrochemical methods into practice: stationary I (E) curves, chronoamperometry, chronopotentiometry, cyclic volammetry (CV), electrochemical impedance spectroscopy (EIS) with determination of kinetic quantities and transport properties of electroactive species.

Content(s)

28h CM/TD: From the formal description of the stationary state to the non-stationary state:
Simple mechanism E to the general case of complex mechanisms

• What tools are used for measurement? Operation of a potentiostat/galvanostat (electronic circuit, ADC, ohmic drop correction, rating, compliance, etc.)
• Cyclic voltammetry (method, description of results according to process kinetics, determination of kinetic and transport quantities)
• Electrochemical impedance spectroscopy (method, representation of results, kinetic and equivalent circuit approach, transport impedance, etc.)

16h Practical exercises: 4 practical exercises are carried out at the electrochemistry platform (Campus), using high-level equipment:

Practical work on ohmic drop and its impact on the determination of kinetic quantities, methods for correcting it
Practical work on determining kinetic quantities by coupling different electrochemical methods (pseudo-stationary CV on EDT, EIS)
Practical work on determining the diffusion coefficient by coupling different electrochemical methods (Chronoamperometry (ring disk, microelectrode), non-stationary CV and pseudo-stationary CV on EDT, EIS)
-Practical work on impedance of linear vs. non-linear systems
