Corso di laurea magistrale in Chimica

The aim of the teaching is to provide students with the knowledge of the principles of electrochemistry and electrochemical techniques (eg chronoamperometry, Cyclic Voltammetry, Square Wave, etc.). Nowadays energy conversion and storage through electrochemical and photochemical techniques have become topics of absolute interest. The aim of the teaching is to provide the basic knowledge and tools that allow to understand the conversion between the different forms of energy that involve the movement of electrons. For example, conversion light - energy, electrical energy - chemical energy, and typically apply the concepts learned to the production of energy (photovoltaic cells and photocatalysis / artificial photosynthesis, fuel cells), and to its storage (batteries and accumulators).

Knowledge of thermodynamics and kinetics aspects of electrochemistry and its applications in the field of energy production (photoelectrochemical cells, artificial photosynthesis, fuel cells) and energy storage (batteries and accumulators), with particular attention to the sustainability and the environment.

Basic reminders of electrochemistry. Transport of matter in solution and theory of electrochemical processes. Electrochemical techniques (Chronoamperometry, polarography, cyclic voltammetry, square wave, etc.). Use of "Digital Simulation" for the study of electrochemical mechanisms. Butler-Volmer's equation. Experimental and applicative aspects of Tafel's relations. Homogeneous chemical reactions associated, modification of the voltammetric response and study of chemical species reactive to the electrode. Electrochemical and chemical reversibility / irreversibility, electrochemical mechanisms. Introduction to the techniques based on the concept of impedance. Applications in the field of energy saving, sustainable development and rational exploitation of resources. Electrochemiluminescence (OLED), classical and third generation photovoltaic cells (DSSC), photocatalysis and artificial photosynthesis (hydrogen production, CO2 reduction), photoelectrochemical cells. Batteries and Accumulators.

The teaching is delivered in the class. It exists the possibility to access video of the lessons of previous years (please contact the teacher)
