Meaning and Definition

To bind (a substance) to a surface via a strong chemical bond rather than simple physical attraction.

A specific type of adsorption where molecules form a chemical bond with the surface of a solid, resulting in a monolayer that is more stable and harder to remove than in physisorption.

Common Mistakes When Using “chemisorb”

  • Using 'chemisorb' interchangeably with 'absorb'.
  • Confusing 'chemisorb' (chemical bond) with 'physisorb' (physical attraction).
  • Incorrect stress: saying /kɪˈmɪsɔːrb/ instead of /ˈkɛmɪsɔːrb/.

FAQ

Frequently Asked Questions

No. 'Absorb' means to take in a substance throughout a bulk material (like a sponge absorbs water). 'Chemisorb' is a surface-specific process where molecules bond chemically to the outer layer of a solid.

Physisorption involves weak intermolecular forces (like van der Waals forces) and is easily reversible. Chemisorption involves stronger chemical bonds (covalent or ionic) and is often irreversible under mild conditions.

Primarily in surface chemistry, heterogeneous catalysis, materials science, and semiconductor physics.

No. The noun form is 'chemisorption'. The past participle 'chemisorbed' is frequently used as an adjective.

To bind (a substance) to a surface via a strong chemical bond rather than simple physical attraction.
