Adsorption isotherms describe how the amount of adsorbate on the catalyst surface varies with its concentration in the surrounding phase at constant temperature. The most common types of adsorption isotherms include:
- Langmuir Isotherm: Assumes monolayer adsorption onto a surface with a finite number of identical sites. - Freundlich Isotherm: An empirical model that describes adsorption on heterogeneous surfaces. - BET Isotherm: Extends the Langmuir model to multilayer adsorption.
