Aims

The aim of this module is to develop the students knowledge of interfacial electrochemistry. This includes both the understanding of fundamental aspects of electrochemistry, as well as techniques for characterising surfaces under electrochemical conditions. Applications of electrochemistry will also be discussed.


Learning Outcomes

The students be knowledgeable on what happens when an aqueous medium is in the vicinity of the surface and be able to describe the structure that occurs in an electrochemical cell. They should be able to describe how cyclic voltammetry and potential step methods can be used to analyse and understand electrochemical reactions. They should be able to perform an electrochemical kinetic analysis of simple and multistep reactions as a means of analysing the mechanism. They should be able to analyse and to answer questions on a number of electrochemical reactions such as metal deposition, electroorganic reactions and adsorption. They should be able to describe fuel cell reactions (hydrogen/air and methanol/air) and be able to analyse fuel cell polarisation curves. They should also be aware of modern spectroscopic methods employed for analysing the solid/liquid interface and be able to describe the level of detail which can be obtained through approp riate application of these techniques.


Syllabus

Liquid solid interfaces. The structure of the electrochemical interface is covered with an analysis of the models of the electrical double layer including a discussion of adsorption at electrode surfaces. Electrochemical kinetics are elaborated upon, including a discussion of the Butler Volmer equation and models for multi-step electro chemical reactions. Mass transport is also covered. Special emphasis is placed on describing electrochemical techniques such as cyclic voltammetry and potential step methods. It is shown how cyclic voltammetry can be used to analyse electrochemical reactions such as adsorption, metal deposition and electroorganic reactions. A number of electrochemical process are considered in detail, including metal deposition and adsorption process.Fuel cell electrocatalytic reactions are discussed in some detail and examples are shown of fuel cells including polymer electrolyte hydrogen-oxygen fuel cells. The role of fuels c ells in the hydrogen economy and as a sustainable technology are discussed. Finally, in-situ techniques for studying electrochemical processes are described.

Teaching and Learning Strategies

Lectures

Tutorial

This module consists of 16 50-minute lectures and 1 tutorial. Associated with the tutorial will be assessed problems for students to demonstrate their ability to apply the knowledge gained in the lectures. The module is backed-up by helpful handouts which are also mounted on VITAL.
