Preferred Label : microporous carbon;
IUPAC acronym : BET;
IUPAC definition : A porous carbon material, usually a char or carbon fibres, which may or may not have
been subjected to an activation process to increase its adsorptive properties. A microporous
carbon is considered to have a major part of its porosity in pores of less than 2
nm width and to exhibit apparent surface areas usually higher than 200 to 300 m2 g-1.;
Scope note : the surface areas determined by thebrunauer–emmett–teller (bet) method are apparent
surface areasonly since the bet adsorption equation is, in principle, not validwhen
micropore filling occurs. the determination of the true surfacearea in the micropores
depends on the method used for the evaluationof the adsorption isotherms and on the
model used for the shape of themicropores (cylindrical, slit-shaped or other).;
