Adsorption and Chemisorption

This lecture covers the concepts of chemisorption and catalysis, focusing on the adsorption of atoms and molecules on solid surfaces due to attractive forces. It explains the differences between physisorption and chemisorption, detailing the energy involved and the formation of chemical bonds. The lecture also discusses examples of chemisorption reactions, such as CO on Pt(111) and CH4 on Ni(111). Furthermore, it explores the Langmuir and BET isotherms, which describe the adsorption of gases on solid surfaces, and the techniques used to measure desorption energies, like Temperature Programmed Desorption (TPD).
