Question

Brief about the importance of surface chemistry.

Accepted Answer

There are many properties of substances particularly of solids and liquids which depend upon the nature of the surface. Surface chemistry deals with phenomena that occur at the surfaces or interfaces. Many important phenomena, like corrosion of metals, electrode processes, heterogeneous catalysis, dissolution and crystallisation occur at interfaces. The subject of surface chemistry finds many applications in industry, analytical work and daily life situations.

Surface Chemistry has a major role in various chemical processes such as:

(i) Enzymatic reactions at the biological interfaces found in the cell walls and membranes.

(ii) In the electronics industry, the use of surface and interface of microchips used in computers.

(ii) In automobile exhausts, the heterogeneous catalysts found in the catalytic converter for cleaning emissions.

(iv) Adsorption on solid or on solution surfaces and colloidal properties are important surface effects which are useful to understand many physical and chemical properties of the substances.
