Summary

Chapter 9 delves deeper into the theories and phenomena related to the adsorption of atoms and molecules at interfaces. It introduces the fundamental concepts related to adsorption: the Gibbs surface excess concentration, the Gibbs adsorption equation, physical vs. chemical adsorption, chemisorption and heterogeneous catalysis, adsorption isotherms, the Brunauer–Emmett–Teller (BET) isotherm and surface area determination, the roles of the adsorbent and the adsorbate, as well as other factors affecting adsorption phenomena.
