It takes place during the second semester of the first year of the Master Degree teaching on Sustainable polyMer And pRocess chemisTry (SMART) . The teaching deals with various aspects of heterogeneous catalysis. The teaching deals with the preparation and characterization of heterogeneous catalysts, their kinetic performance and the influence of phenomena that limit the overall reaction rate. The approach is pragmatic and oriented to the development of sustainable industrial processes. AIMS AND CONTENT LEARNING OUTCOMES Aim of the teaching is to provide the basic knowledge on the preparation, characterization, and application of heterogeneous catalysts, also through practical laboratory experiences, introducing the student to the definition of sustainable processes. AIMS AND LEARNING OUTCOMES At the end of the teaching the student will have to know the main methods of preparation and characterization of catalysts and be able to evaluate the influence of mass transfer phenomena on the reaction rate of heterogeneous catalytic reactions. Thanks to the laboratory activities, the student will be able to work in a group, presenting in written form of reports the results of experimental activities both summarizing the procedures adopted and analyzing and trying to interpret the observations and data obtained. PREREQUISITES Fundamentals of general chemistry, chemical thermodynamics and kinetics. TEACHING METHODS - Lectures (32 hours) - Laboratory experiences (mandatory attendance) (26 hours): Laboratory experiences are addressed by multi-student working groups (e.g. 3-4). The student will have to interact both within their own working group and at the same time it stimulates the interaction between the working groups in the reporting phase. Laboratory experiments on the preparation of catalysts allow groups to adapt and propose the synthesis procedure. Each working team, for each experience should write a short draft report. and within the end of the teaching one or two full reports (as agreed with the teacher) dealing with some of the experiences should be delivered by each working group. The approach of the whole laboratory is interactive both among students and with the teacher.

TEACHERS AND EXAM BOARD ANTONIO COMITE Ricevimento: On appointment fixed by email (antonio.comite@unige.it) or phone call. Exam Board ANTONIO COMITE (President) CAMILLA COSTA ORIETTA MONTICELLI ALBERTO SERVIDA SILVIA VICINI LESSONS LESSONS START The teaching is foreseen to start in the II semester of the academic year starting on 24/02/2025. The timetable of the lessons will be published on the portal https://easyacademy.unige.it/portalestudenti/ and usually takes place in theoretical terms of Monday (9-11) and Wednesday (12-13) and in laboratory sessions on Monday afternoon (14-18) as indicated by the teacher. Class schedule The timetable for this course is available here: Portale EasyAcademy EXAMS EXAM DESCRIPTION Oral examination and evaluation on reports on the laboratory experiences. The discussion during the oral examination will begin from the laboratory experiences and then it will cover the main themes of the teaching: synthesis, characterization and testing of heterogeneous catalysts and applications. Grading System: Final oral exam: 60%; Laboratory reports: 40% For students disabilities or with specific learning disabilities (DSA), the examination procedures are in line with the University regulations for the performance of the examinations (https://unige.it/disab-dsa). The DSA student can use concept maps previously agreed with the teacher. ASSESSMENT METHODS The commission is composed of two components and one of them is the teacher of the teaching. The duration of the examination is not less than 30 min. In this way the commission is able to verify the achievement of the learning outcomes. The student should know the main methods of preparation and characterization of catalysts and be able to interpret the influence of mass transfer phenomena on the reaction speed of heterogeneous catalytic reactions both from a theoretical basis and from the laboratory experiences. If the learning outcomes will be not achieved the student is invited to study again and better following some teacher suggestions and explanations. For students with disabilities or with Learning Disability (DSA), the examination methods are consistent with the University regulations for the conduct of the exams (https://unige.it/disabilita-dsa). FURTHER INFORMATION Students who have valid certification of physical or learning disabilities on file with the University and who wish to discuss possible accommodations or other circumstances regarding lectures, coursework and exams, should speak both with the instructor and with Professor Sergio Di Domizio (sergio.didomizio@unige.it), the Department’s disability liaison.
