1. to bind (a substance) to a surface through chemical bonding rather than physical adhesion
Usage: technical; chemistry

Examples

• The gas molecules chemisorb onto the catalyst surface, forming strong chemical bonds.
• When oxygen chemisorbs on the metal, it creates a stable oxide layer.
• The enzyme chemisorbs the substrate at its active site before catalyzing the reaction.
• Carbon monoxide chemisorbs irreversibly to the platinum electrode.
• The material chemisorbs pollutants more effectively than competing adsorbents.
