Physisorption or physical adsorption is a type of adsorption in which the adsorbate adheres to the surface only through Van der Waals (weak intermolecular) interactions, which are also responsible for the non-ideal behaviour of real gases. It is characterised by:
- Low ambient temperature, always under the critical temperature of the adsorbate;
- Type of interaction: Intermolecular forces (van der Waals forces);
- Low enthalpy: ΔH < 20 kJ/mol;
- Adsorption takes place in multilayers;
- Low activation energy.
- The energy state of adsorbate is not altered.
