1. Chemisorption

   Chemisorption is a kind of adsorption which involves a chemical reaction between the surface and the adsorbate. New chemical bonds are generated at the adsorbent surface. Examples include macroscopic phenomena that can be very obvious, like corrosion, and subtler effects associated with heterogeneous catalysis, where the catalyst and reactants are in different phases. The strong interaction between the adsorbate and the substrate surface creates new types of electronic bonds.In contrast with chemisorption is physisorption, which leaves the chemical species of the adsorbate and surface intact. It is conventionally accepted that the energetic threshold separating the binding energy of "physisorption" from that of "chemisorption" is about 0.5 eV per adsorbed species. Due to specificity, the nature of chemisorption can greatly differ, depending on the chemical identity and the surface structural properties. The bond between the adsorbate and adsorbent in chemisorption is either ionic or covalent.

1. chemisorption

   Chemisorption is a type of adsorption whereby a molecule or atom is held on a surface by chemical bonds. This process typically involves either transfer of electrons or sharing of electrons between the adsorbate (the substance being adsorbed) and the substrate (the surface on which adsorption takes place). Chemisorption usually occurs at specific sites on the surface and is often used in various industrial applications and in many chemical reactions.
