The course presents, with emphasis to fundamental physicochemical principles, the basic principles of electrochemical thermodynamics and physical and chemical kinetics as applied to electrochemical conversion systems: batteries, fuel and biofuel cells, electrolysers, and photoelectrochemical cells.
1) Summary of the principles of chemical and electrochemical thermodynamics of relevance to electrochemical energetics.
2) Outline of basic concepts of solid-state physics of metals and semiconductors.
3) Thermodynamics of the metal-electrolyte and semiconductor-electrolyte interface and of electrochemical cells on the basis of the electrochemical potential concept.
4) Transport properties of electricity carriers in ionic and electronic conductors, migration and diffusion.
5) Electrochemical kinetics and catalysis at metal and semiconductor electrodes, introduction to complex multi-step electrode reactions, adsorption effects.
6) Electrochemical double layer at metal and semiconductor electrodes
7) Comparative description of electrochemical systems: primary and secondary batteries, fuel and biofuel (enzymatic and microbial) cells, water electrolysers, electrochemical supercapacitors.
8) Comparative description of photoelectrochemical systems based either on direct semiconductor photoexcitation or on dye sensitisation of semiconductors: electrochemical photovoltaic (electricity-producing) cells, photoelectrosynthetic cells (including e.g. photoelectrochemical water splitting and electrochemical carbon dioxide reduction), photocatalytic cells (including photoelectrochemical fuel and biofuel cells).
9) Hybrid photovoltaic-electrochemical and photovoltaic-photoelectrochemical sysytems for solar fuel generation and solar energy storage.
10) Application of electrochemical principles to microdispersed photocatalytic systems for energy conversion.
Electrochemical cells, photoelectrochemical cells, electrochemical thermodynamics, electrochemical kinetics, overvoltage, solar energy conversion and storage, migration, double layer.
