Definition

1. Adjective:
   • Having the capacity or property to adsorb substances primarily through chemical forces rather than physical forces. This describes a specific type of adsorption where a strong chemical bond forms between the surface and the adsorbed molecules.

Usage and Examples

• Adjective:
  • The chemisorptive properties of the catalyst are crucial for the reaction to proceed.
  • This material's surface is highly chemisorptive, making it excellent for gas purification.
  • Researchers studied the chemisorptive behavior of hydrogen on the metal alloy.

Advanced Usage

• Technical Context: The term is primarily used in chemistry, surface science, materials science, and chemical engineering to describe the nature of adsorption on a surface.
  • The chemisorptive process is often characterized by a high heat of adsorption and specificity.
• Contrast with Physisorption: Often used to contrast with "physisorptive" (adsorptive by physical forces like van der Waals forces).
  • Unlike physisorption, chemisorptive bonding involves electron transfer or sharing.

Variants and Related Words

• Chemisorption (noun): The process or phenomenon of adsorbing by chemical forces.
  • The chemisorption of oxygen on the metal surface created a stable oxide layer.
• Chemisorb (verb): To adsorb by chemical forces.
  • Certain gases chemisorb onto platinum at room temperature.
• Chemisorptively (adverb): In a chemisorptive manner.
  • The gas was chemisorptively bound to the substrate.

Synonyms

• Chemically adsorptive: Having the ability to adsorb via chemical bonding.
• Reactive adsorption: Adsorption involving a chemical reaction at the surface. (Note: This is a more descriptive synonym.)

Antonyms

• Physisorptive: Having the capacity to adsorb by physical forces.
• Non-chemisorptive: Lacking the property of chemisorption.
