chemosorption
Noun: * Chemosorption: A type of adsorption, especially an irreversible one, where a substance (typically a gas or liquid) adheres to a surface primarily through chemical bonding forces rather than weaker physical forces. It involves the formation of chemical bonds between the adsorbate and the adsorbent surface.
Chemosorption is a scientific term used primarily in chemistry, physics, and materials science to describe a specific surface phenomenon. It contrasts with physisorption, which involves weaker physical forces like van der Waals interactions. * The process of chemosorption is critical for the functioning of many industrial catalysts. * A key characteristic of chemosorption is that it often involves a significant activation energy and results in a monolayer of the adsorbed substance.
- The chemosorption of oxygen onto a clean metal surface can lead to the formation of a stable oxide layer.
- Researchers studied the chemosorption of carbon monoxide on the platinum catalyst.
- The irreversible nature of the chemosorption process makes it suitable for certain gas purification applications.
- Chemisorptive (adjective): Describing a property or process related to chemosorption.
- The material's chemisorptive capacity for hydrogen was remarkably high.
- Chemisorb (verb): The act of binding via chemosorption.
- Nitrogen molecules chemisorb onto the iron catalyst before reacting.
- Chemisorption: A direct synonym for chemosorption. The terms are often used interchangeably.
- Adsorption: The broader general process of a substance accumulating on a surface, which includes both chemosorption and physisorption.
- Physisorption: Adsorption via physical forces, a process distinct from chemosorption.
- Sorbent: The material on which adsorption occurs.
- Sorbate: The substance that is adsorbed.
