CH 621 Trends In Analytical Chem (Electrochemistry)
Prerequisites for this course are general chemistry (CH101, 102). All students are assumed to have some background in half reaction potentials, standard potentials, redox reactions, and electroanalytical chemistry at the general level of undergraduate courses (e.g., quantitative analysis). Some ability in computer programming, at the minimum use of spreadsheets, like Excel (to carry out the digital simulations taught in the course) is also assumed.
This course is designed to teach the fundamental aspects of electrochemistry and the application of electrochemical methods to chemical/engineering problems. Special emphasis will be given to the study of electrode reaction mechanisms and the interpretation of electrochemical results (e.g., cyclic voltammetry) for organic and inorganic systems. A rigorous consideration of voltammetric and coulometric methods and several topics of interest in electrochemistry including modified electrodes, photoelectrochemistry, scanning electrochemical microscopy and electrogenerated chemiluminescence etc will be undertaken. We will also introduce the concept of AC impedance, solar cell and fuel cell at the end of the course. There are hands-on activities (e.g., CVs, solar cell, electrolysis, fuel cell, energy transformation, rotating disc electrode) provided to enhance the learning.
Student Learning Outcomes
This course will help graduate students interpret various electrochemical results (e.g., cyclic voltammetry) for organic and inorganic systems. Students are expected to be capable of using digital simulation and electrochemistry theory to understand electrochemical phenomenon; secondly, students will be able to apply electrochemical methods to solve chemistry and chemical engineering problems existing at a solid-liquid interface; third, student will have a comprehensive understanding of analytical chemistry application of electrochemistry and learn how electrochemistry is used in sensors for ultrasensitive detection; Several types of devices such as fuel cell, light emitting electrochemical cell and solar cell will be introduced in order to enhance their understanding of the principles of electrochemical systems. Students are expected to have the ability to develop their own interests further based on what we will learn through the course by reading literature and conducting research in these important fields.
