This paper presents the theories that are the most widely used in surface science. The BET theory is belonged to them and used for the calculation of surface areas of solids by physical adsorption of gas molecules. Several similar methods are used for the micropore characterization such as V–t method, the Alpha–s, the MP, the DR, the DA, the HK and the SF. Also, the Pore Size Distribution (PSD) of porous media can be calculated with the use of several methods. Furthermore, mercury porosimetry gives information such as surface area. This study describes the theoretical basis of the basic theories for micro-, meso– and macro- pores characterization and provides information which can be extracted from the mentioned techniques.
