CY2010 Kinetics and Catalysis


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)
