Catalytic Processes
A.Y. 2023/2024
Learning objectives
The course aims to provide the bases for understanding the chemical transformations that take place with the action of homogeneous and heterogeneous chemistry catalysts and biological catalysts (enzymes). To this end, along with the description of the theoretical concepts of catalysis, examples of important catalytic processes of environmental interest and industrial chemistry will be described.
Expected learning outcomes
The student will be able to acquire kinetic and molecular knowledge on the reactive processes that occur in the presence of "third elements" (homogeneous, enzymatic and heterogeneous catalysts) that increase the reaction speed and improve the selectivity of the reactive process. These concepts will be useful for tackling more advanced courses in industrial chemistry.

Teaching methods
Teaching will take place through lectures aimed at providing knowledge tools and solving problems related to the problems of chemical reactivity.
The teaching material and the operational tools proposed will be made available in digital format at Ariel website so that students can re-elaborate them according to their own didactic needs.

Assessment methods and Criteria
Students' learning will be verified with an oral exam that will concern the topics covered in Sections A-D. An in-depth work on a topic chosen by the student among those presented during the sections E-F will be appreciated.
In addition, students can take two intermediate oral tests. The first intermediate test will take place at the end of Module D and will consist of an oral discussion (single question) on a subject covered in Modules A-D. The second test will consist of a critical discussion of a team project work (max 3 members per team). These intermediate tests replace the final examination. The final assessment in this case will consist of the weighted average of the votes assigned to the two tests.
In all the tests (intermediate or final) the evaluation will be a mark out of thirty. The evaluation parameters will be: ability to argue; critical reasoning skills; quality of exposure, competence in the use of specialized glossary.
