Inhalt:
The lecture, Übung and Praktikum advanced electrochemistry provides a fundamental insight into
electrochemical systems and discuss advanced electrochemical methods. 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, required for the
understanding of electrochemical reactor technology. They will also get an insight into the fundamental
research problems of modern electrochemistry.
In the Übung practical electrochemical systems will be discussed that are either already of great
economic importance or will become crucial in future applications. In this part of the course students
will gain knowledge on the most relevant applied electrochemical research topics, will have a clear view
on the versatility of electrochemical devices and have an understanding of electrochemistry based
energy systems and their potential. Several technologies of importance in energy conversion systems
and the production of added-value chemicals like electrolysers, fuel cells, flow batteries,
supercapacitors, chloralkali process, organic electrosynthesis, aluminum production, but also corrosion,
metal deposition, ectroanalysis, electrochemical sensors, lithography galvoforming, semiconductors,
information storage, bioelectrochemistry, photoelectrochemistry, conducting polymers, will be
discussed. Setup of the lecture:
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, electrifiedinterfaces: double layer theories, adsorption (adsorption isotherms), surface excesses,electrocapillary equation, electrokinetic properties
Electrochemical kinetics (3 lectures)Tafel-equation, Butler-Volmer equation, theories of electron transfer, transition state theory, introduction to electrocatalysis (single crystals), rate-coverage relations
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 …), electrochemistry coupled with spectroscopic techniques (in situ spectroelectrochemical techniques: UV-VIS, IR, X-ray, Raman etc), mass spectrometry, EQCM etc; intro to the second semester courses
