In addition, the surface area of MOFs that are obtained by implementing different approaches, such as grand canonical Monte Carlo simulations, calculations from the crystal structures or based on experimental N 2, Ar, or CO 2 adsorption isotherms, are compared and evaluated. In this review, the suitability of the BET method is discussed for MOFs that have a diverse range of pore widths below the diameters of N 2 or Ar and above 20 Å. Several researchers have evaluated the BET method to gain insights into the usefulness of the obtained results and interestingly, their findings are not always consistent. ![]() ![]() Since these materials are highly porous, the use of the BET theory can be problematic. Surface area determination with the Brunauer–Emmett–Teller (BET) method is a widely used characterization technique for metal–organic frameworks (MOFs).
