Electrochemistry (Echem)5 ECTS
(englische Bezeichnung: Electrochemistry)
(Prüfungsordnungsmodul: Electrochemistry)

Lehrveranstaltungen:

• • Electrochemistry
    (Vorlesung, 2 SWS, Karl J. J. Mayrhofer et al., Do, 12:15 - 13:45, T 0.75)
  • Exercise Electrochemistry
    (Übung, 3 SWS, Dominik Dworschak et al., Mo, 8:15 - 10:30, LSTM-SR)

Inhalt:

The lecture and Übung of the first semester provide a fundamental insight into electrochemical systems and discuss basic thermodynamics, double layer theory, conductance and migration etc. Based on this knowledge, students will be able to understand electrochemical problems, suggest methods to solve them and understand the background of many practical electrochemical systems and applications. Moreover, they will receive an intensive insight into electrochemical analytical methods necessary to investigate electrochemical reactions. In the practical part they will apply this knowledge and investigate standard electrochemical reactions, and will also design a program to model the results.

• Electrochemical thermodynamics (5 lectures)

introduction (scope and role of electrochemistry, short history), electrochemical potentials, Nernst-equation, electrodes, conductance, transference number, mobility, solvation of ions, the Born-equation, Debye-Hückel theory, junction potentials, ion selective electrodes (concept of pH, the glass electrode, other ion selective electrodes), transport phenomena, electrified interfaces: double layer theories, adsorption (adsorption isotherms), surface excesses, electrocapillary equation, electrokinetic properties

• Electrochemical methods (7 lectures)

electrochemical cells/reactors, electrochemical instrumentation, potential step methods, potential sweep methods, galvanostatic methods, stripping analysis, hydrodynamic methods (RDE, RRDE), impedance (1 lecture), scanning techniques (electrochemical STM, SECM, SFC, AFM …), intro to the second semester courses

• Electrochemistry in applications (3 lectures)
  

Corrosion, metal deposition (coatings); Electroanalysis, electrochemical sensors, modified electrodes; Lithography galvoforming, semiconductors, information storage, bioelectrochemistry, photoelectrochemistry, conducting polymers
Student competencies achieved:

• Understand the thermodynamic fundamentals of electrochemical processes

• Knowledge of modern electrochemical methods and their application

• Interpret data from electrochemical measurements
