CY2010 Kinetics and Catalysis


Objectives:

The objective is to introduce the concepts of chemical kinetics and catalysis. The students will be able to apply the concepts to homogeneous and heterogeneous catalysis including electrocatalysis.

Course Contents:

Chemical Kinetics: Recollection of basic concepts of chemical kinetics; Mechanism of chemical reactions (steady state approximation, unimolecular decomposition-Lindemann mechanism) and Thermodynamic treatment of Transition State Theory. (10 lectures)Homogeneous Catalysis: Reactions in solution, Influence of dielectric constant and ionic strength, salting-in, salting-out and kinetic isotope effects; Acid-base catalysis; Enzyme catalysis (Michaelis-Menten kinetics, turnover number, Lineweaver-Burke plot, inhibition of enzyme action-competitive, noncompetitive, uncompetitive); Micellar catalysis. (12 lectures)Heterogeneous Catalysis: Structure of solid surfaces, Adsorption isotherms (BET, Freundlich and Langmuir, surface area determination); Kinetics and mechanisms of chemical reactions on surfaces, unimolecular reactions, bimolecular reactions (Langmuir-Hinshelwood and Eley-Rideal mechanisms); Concept of active site, turnover frequency, effect of surface structure on reactivity, surface restructuring, structure dependence and independence of catalytic reactions (Fe catalyst for NH3 synthesis); Supported and unsupported catalysts; Promoters and poisons. (16 lectures)Electrocatalysis: Electrode-electrolyte interface (double layer theory); Mass transfer and charge transfer at the interface (cyclic voltammetry and rotating disk electrode); Single-step and multi-step reactions (symmetry factor and transfer coefficient); Butler-Volmer and Tafel kinetics. (10 lectures)
