AbstractElectrolytes: conductivity, transfer number, diffusion, migration, convection. Electrode/electrolyte interface, Nernst equation, potential vs. turnover. Kinetics, overpotential. Electrocatalysis. Porous electrodes, solid state electrochemistry, current density distribution. Electroanalytical techniques. Applications: electrolysis, galvanotechnics, batteries; electrosynthesis, sensors, corrosion.
ObjectiveTowards the end of the course the students will understand the basics of electrochemistry and will be able to describe and calculate electrochemistry-related matters in industrial processes and products.
ContentHistoric development and applications of electrochemistry. Electrochemical cells: electrodes, electrolyte, charge transfer, material flux, electrochemical conversion. Electrolytes: structure of solutions, conductivity, transfer number, solid and polymer electrolytes, transport processes in the electrolyte (diffusion, migration, convection, limiting current density). Cell voltage, electrode potential, potential series. Reversible electrode reactions: Nernst equation, potential vs. turnover. Electrode / electrolyte phase boundary: electrochemical double layer, exchange current density. Kinetics of electrochemical reactions: global and local current density, overpotential, Tafel equation, Butler / Volmer equation. Electrocatalysis. Porous electrodes, solid state electrochemistry, current density in the electrodes and in the electrolyte, electrochemical engineering. Electroanalytical methods: chronopotentiometry, cyclovoltammetry, electrochemical impedance measurements. Applications: electrolysis, galvanotechnology, batteries, ultracapacitors, fuel cells, electrosynthesis, electrochemical sensors, corrosion.
