The course aims to provide students with the concepts of chemical catalysis by providing for the use of environmentally friendly methods and alternative synthetic pathways, in the field of Sustainable Chemistry. Approaches based on both the innovation of chemical substances acting as catalysts and the use of unconventional reaction conditions will be illustrated. Emphasis will be placed on possible multidisciplinary approaches and on the most modern technologies that allow sustaining reactions in environmentally sustainable conditions.
1. Course introduction, green chemistry definition, and historical development. The green chemistry approach to reduce chemical risk.
2. Green chemistry: re-imagining chemistry. The challenge of sustainability as a driving force for green chemistry. Toxicity and ecotoxicity; green chemistry and EU's REACH regulation; introduction to toxicology; chemical exposure and dosage.
3. 12 Principles of green chemistry.
4. The periodic table of the elements
5. Chemical reactions and stoichiometry: the importance of balancing chemical equations.
6. The problem of waste and byproduct production by chemical reactions or processes.
7. Green chemistry metrics for reactions and processes: atom economy, E factor,...
8. Catalysis: introduction to catalysis in the context of green chemistry; heterogeneous catalysts; homogeneous catalysis; phase transfer catalysis; biocatalysis, and photocatalysis.
9. Organic solvents and working without solvents.
10. Renewable feedstocks.
11. Green chemistry and energy; green technologies and alternative energy sources.
12. Designing greener processes.
13. Life cycle assessment.
14. Real-World cases in green chemistry and industrial case studies.

The course will be concluded with an examination where the student demonstrates proficiency in the subject matter of the course, according to the specified “Learning outcomes”. The written examination consists in multiple-choice and open-ended questions, as well as in calculation exercises. The student may ask the instructor for a complementary oral test after the written test.
