A new analysis method has been developed for the determination of the pore size distribution of porous carbons from nitrogen adsorption measurements. The method is based on a molecular model for the adsorption of nitrogen in porous carbon. It allows, for the first time, the distribution of pore size

In the present work, two kinds of porous silicas (PS-C16 Two kinds of the porous silicas with uniform and cylindrical and PS-C18) were synthesized from the calcined Na 4 SiO 4 pores were prepared from calcined Na 4 SiO 4 and cationic surfacand the cationic surfactant of [C 16 H 33 N(CH 3 ) 3 ]Cl or
The adsorption isotherms of N 2 gas at 77 K and CCl 4 vapor at 283.1 5 , 298.1 5 , and 308.1 5 K were measured for six samples of the mesoporous silicas having uniform cylindrical pores (MCM-41). The pore radii of the six samples (r p ), which were evaluated from the ฮฑ s plots of the N 2 isotherms,
