Surface Chemistry
Surface chemistry is the branch of physical chemistry that investigates chemical and physical phenomena occurring at interfaces between distinct phases, where asymmetric forces create properties fundamentally different from the bulk.
Overview
Atoms and molecules at surfaces experience incomplete bonding environments, giving rise to phenomena such as adsorption, wetting, surface tension, and catalysis. Heterogeneous catalysis, in which reactions occur at a solid catalyst interface, represents one of the field's primary applications.
Why it matters
Surface chemistry informs chemical processes such as the Haber–Bosch ammonia synthesis, petroleum refining, and emissions reduction in catalytic converters. It also supports semiconductor fabrication, battery electrode engineering, and protective coating development.
