Gas adsorption: surface area and pore size determination
Gas adsoption is an essential technique for the characterization of a wide variety of porous materials.One of the most important characteristics of these materials is the high surface area they contain in the porous framework. MOF type materials are one of the most studied with gas adsorption, but it is also a powerful tool to characterize carbons and many others micro-, meso-, and macroporous materials. This talk is intended to give a general view of the technique and its applications, how we should proceed to prepare the sample before the measurements, what type of isotherms we can obtain and the models we can use to determine the surface area and pore size with experimental isotherms (BET, Alpha-S, BJH, DH, DR, t method...).
