The Brunauer, Emett and Teller (BET) method explains the physical adsorption of gas molecules (N2 or CO2) to a solid surface and is based on the fact that the adsorbed gas molecules tend to form a fine layer which covers the whole of the surface of the sohd. Thus, it enables us to measure the specific surface area (mVg) of the sample (generally powders) and the distribution of its pores as a function of their size. The acronym BET comes from the initials of the surnames of S. Brunauer, P. H. Emmett and E. Teller - American scientists who, in 1938, published the first article on the BET method. 

Of particular interest is the material MCM-41, which has a structure consisting of highly ordered, two-dimensional (non-intersecting) hexagonal arrays of very uniform pores (Figure 6.1). MCM-48 is similar, but with a cubic structure. The acronym MCM has never been explained, and the suggestion Mobil Crystalline Material seems unlikely for a near-amorphous solid. MCM-41 is extremely porous, because up to 80% of the solid material can be empty space, and the pore walls have an enormous surface area. A value of twelve hundred square metres per gram, an area equivalent to more than a tennis court, would not be unusual ... 

Davis and his group developed in 1989 a new approach to the increase in the interfacial area by immobilizing the water-soluble coordination complex in a thin film of water maintained on a high surface-area hydrophilic solid [12-16]. It has been called supported aqueous phase catalysis and sometimes by its acronym SAPC. ...
