Electrochemistry
A.Y. 2020/2021
Learning objectives
Students will face with thermodynamics and kinetics aspects of electrochemistry, discussing both theoretical and application-oriented phenomena in connection with electrolytic solutions and new electrode materials; with semiconductors; with ionic exchange membranes. Advanced electrolytic processes for energy conversion and environmental treatments will be also presented and discussed.
Expected learning outcomes
The student will be able to define and calculate the potentials of the galvanic and cell semi-elements, understand the parameters that affect the overpotentials, the effect of the solvent and the electrolyte, and the fundamental parameters of the limit law of Debye-Huckel; will be able to use the Butler Volmer equation and the Tafel line. It will include the use of semiconductors as electrodes. He will master the processes of energy conversion and membrane processes
