This article presents a comprehensive overview on the formation and investigation of porous systems and surface area characteristics of micro-, mesoporous zeolitic materials based on aluminum phosphate materials, microporous carbons, building materials in terms of cement stone and natural soil samples. The results of the gas sorption experiments performed on the different materials will be discussed in detail, especially when sorption phenomena like kinetic restricted diffusion, sorption hysteresis and materials where the pore system is undergoing a structural deformation with time can be observed.
