Several models exist to describe adsorption phenomena: - Langmuir Isotherm: Assumes monolayer adsorption on a surface with a finite number of identical sites. - Freundlich Isotherm: Describes adsorption on heterogeneous surfaces. - BET Theory: Extends the Langmuir model to multilayer adsorption.
These models help in understanding the adsorption behavior and in predicting the performance of catalysts under different conditions.
