Definition of chemisorption in English:

chemisorption

noun

Chemistry
  • [mass noun] Adsorption in which the adsorbed substance is held by chemical bonds.

    • ‘This model is most appropriate when interactions between the MC and its environment are purely surface phenomena, as in the chemisorption of thiol molecules on the smooth surface of a gold-coated cantilever.’
    • ‘Intact DOPA, particularly near the interface, may be essential for good chemisorption to polar surfaces.’
    • ‘The authors write, ‘Both the physisorption and the chemisorption play important roles in optimizing the hydrogen storage.’’
    • ‘These data support what has already been suggested: that the DOPA side-chain in proteins serves two important roles in adhesion-the formation of cross-links and interfacial complexes in chemisorption.’
    • ‘Chemists make a distinction between chemical adsorption, or chemisorption, characterized by the formation of chemical bonds with the substrate, and physical adsorption or physisorption, which results from the van der Waals force.’

Origin

1930s: from chemi- + a shortened form of adsorption (see adsorb).
