chemisorption
chemical process
Also known as: chemical adsorption
Quick Summary
Chemisorption is a process where molecules are taken up and held by chemical forces, often irreversibly, onto the surface of a solid. This is distinct from physical adsorption, which relies on weaker van der Waals forces. Chemisorption typically occurs at higher temperatures than physical adsorption and is a slower process, often involving an energy of activation. The term is derived from "chemical" and "adsorb".12
