CATALYSIS AND PHOTOCATALYSIS FOR THE ENVIRONMENT AND ENERGY
Academic Year 2023/2024 - Teacher: Salvatore SCIRE'Expected Learning Outcomes
The course aims to provide the fundamental knowledge of catalysis and photocatalysis, with special attention to the application of (photo)catalysts in the fields of energy production and environmental protection.
Course Structure
Classroom lessons with numerical exercises
Should teaching be carried out in mixed mode or remotely, it may be necessary to introduce changes with respect to previous statements, in line with the programme planned and outlined in the syllabus.
Learning assessment may also be carried out on line, should the conditions require it
