chemisorptive
Học thuậtThân thiện
Definition
- 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.
Adjective
- having the capacity to adsorb by chemical as contrasted with physical forces
