Surface chemistry is the study of chemical reactions and interactions that occur at the interface between different phases, such as solid-liquid, solid-gas, or liquid-gas. It focuses on how molecules behave on surfaces, which can differ significantly from their behavior in bulk materials. This field is crucial for understanding processes like catalysis, corrosion, and adsorption. Researchers in surface chemistry examine factors like surface energy, adsorption isotherms, and the effects of surface roughness. Applications of surface chemistry are widespread, impacting industries such as catalysis, materials science, and nanotechnology. Understanding these interactions helps improve products and processes in various fields.
