Content, Learning Outcome and Preconditions

Content

Solid-liquid interfaces play an important role in many physico{chemical, biological and technical systems (e.g. energy conversion and storage, signal transduction in cells). The focus of this course lies on the structure-reactivity relationships of solid-liquid interfaces. We will start with a discussion of models describing the charge transfer kinetics of electrodes (Butler-Volmer, Marcus, etc.). Then important characterization methods for charged interfaces will be discussed such as cyclic voltammetry, impedance spectroscopy, potential and current step methods. - Classical theories of charge transfer at interfaces: Tafel's law, Butler-Volmer theory - Molecular approaches to describe charge transfer: Marcus theory - Potential and current step methods, chronoamperometry, chronopotentiometry - Characterization methods based on the concept of impedance and transfer func- tions - Equivalent circuits of electrochemical interfaces - The role of mass transport (migration, diffusion, convection) for the reactivity of interfaces, Poisson-Nernst-Planck equations - Digital simulation of charge transfer processes at solid-liquid interfaces - Industrial applications: electroplating, corrosion protection, sensor applications based on electrochemical detection principles

Learning Outcome

After participation in the module the student is able to: 1. Describe important properties characterizing the dynamics of interfaces (heteroge- nous rate constants, exchange current densities, etc.) 2. Discuss structure-reactivity relationships of interfaces, especially electrochemical interfaces 3. Understand the fundamentals and limitations of important characterization techniques for the reactivity of interfaces such as current-voltage curves, relaxation methods

Module Exam

Description of exams and course work

In an oral exam the learning outcome is tested using comprehension questions and sample problems.

In accordance with §12 (8) APSO the exam can be done as a written test. In this case the time duration is 60 minutes.

Exam Repetition

The exam may be repeated at the end of the semester. There is a possibility to take the exam in the following semester.
