This improves your skill in lecturing. If a couple of people feel that they need help in structuring their talk, they should follow a course in which a practice lecture is incorporated. They present well defined micropore structures that make them interesting agent for separation purpose. Moreover, their mechanic and thermic stability properties have confirmed them with an important position in heterogeneous catalysis. Another major property of zeolites favored them with this position.
Zeolites display high capability to achieve selective reactions.
This product selectivity issues from their micropore structure that induces reactant discrimination, transition state selectivity and differences in product diffusivity. Progresses in computer power as well as in quantum chemical codes allow for investigation of zeolite framework effect on reactivity. It will be presented several examples that show how zeolite catalyst steric constraints and electrostatic contribution change reaction energy diagrams. Isomerization and alkylation reactions of aromatics, cracking reaction of thiophenic derivatives and olefins chemisorption reactions catalyzed by acidic zeolite will be considered.
