Last update: Bystroň Tomáš doc. Ing. Ph.D. (22.01.2015)
The course is focused on fundamental principles and laws of electrochemistry. Basic terms and definitions will be introduced in the beginning of the course. Consequently the electrolyte behaviour, equilibria in electrochemical systems, kinetics of electrochemical processes and electrochemical reaction mechanisms will be discussed. Students are expected to have basic knowledge in the field of physical chemistry.
Aim of the course -

Students will be able to:

• use basic terms of electrochemistry

• evaluate redox equilibria in simple systems

• qualitatively and quantitatively describe processes taking place in electrochemical systems

1. Introduction - basic terms and definitions (electric charge, electrostatic field, basic laws of electrochemistry, electrochemical potential, steps of electrochemical reaction)

2. Electrolytes (definitions, solid electrolytes, electrolyte solutions, melts, ionic liquids, solvation, equilibria in electrolyte solutions, weak and strong electrolytes, dissociation, association, autoprotolysis, pH)

3. Activity coefficients in electrolyte solutions (Debye-Hückel theory, ionic strength)

4. Mass transport in electrolyte solutions (diffusion, migration, convection, electrolyte conductivity, Nernst-Planck equation, liquid junction potential)

5. Solid electrolytes, ion-selective polymer electrolytes (structure, charge transport mechanism, comparison with electrolyte solutions)

6. Electrochemical equilibria on phase interface (Nernst equation, general conditions of electrochemical equilibrium on phase interface - equilibrium electrode potential, cell voltage, Donnan potential)

7. Redox equilibria evaluation (Pourbaix diagrams, their construction and utilisation)

8. Classification of electrochemical systems (Electrolyser, galvanic cell, electrochemical pump, electrolyser and galvanic cell voltage, anode and cathode potential, overvoltage, efficiency of electrochemical system)

9. Electrodes (definition, types of electrodes, reference electrodes, ionic selective electrode, pH electrode, principles of operation)

10. Electrode double layer (Helmholtz model, Gouy-Chapman and Stern models, specific adsorption of ions)

11. Adsorption (Langmuir, Frumkin, Temkin)

12. Kinetics of electron transfer process (partial currents, symmetry factor, exchange current density, general equation of polarisation curve)

13. Kinetics of electron transfer process (Butler-Volmer equation and its linearisation, Tafel equation, symmetry factor vs. charge transfer coefficient)

14. Electrochemical reaction mechanism - electrochemical reaction as a sequence of elementary steps (single electron transfer, preceding and consequent chemical reaction, formation of radical-cation (anion) and radical, dimerisation, reaction with electrophile and nucleophile)
