Learning objectives

Catalysis is the key to efficient chemical processing. Catalysis is an interdisciplinary coherent subject, unified by concepts of chemical structure and reactivity, kinetics and transport phenomena.
It is the aim of the course to give an unitary understanding of the catalytic phenomena.
The course of Environmental Catalysis aims to consider the applications of catalysis in the field of processes for the reduction of emissions and the abatement of gaseous pollutants. More generally, it focuses on the realisation of more sustainable processes in view of the protection of environment.



Course unit content

Introduction, catalytic principles, definitions: TON, TOF, green chemistry, atom economy.
Homogeneous catalysis with transition metal catalysts. Selective couplings (Heck, Suzuki) catalysed by transition metal.

Heterogeneous catalysis: fundamentals and characterization techniques.
Shape selectivity; zeolites.
Catalysis and the environment.
Contribution of catalysis towards the reduction of atmospheric air pollution: carbon dioxide, CFCs, nitrous oxide, ozone.
