“…The specific surface area, S BET , was calculated using the multiple-point Brunauer-Emmett-Teller (BET) method, and the total pore volume, V pore , was evaluated from nitrogen uptake at a relative pressure of approximately 0.99. The micropore volume, V micropore , was estimated using the HK methods [24]. Micropore size distributions from 0.35 to 2 nm were determined using non-local density functional theory (DFT) [25].…”

“…Barrett-Joyner-Halenda (BJH) desorption pore size and volume analysis [23] were applied to determine the pore size distribution of the mesopores, while the Horvath-Kawazoe method [24] with Saito-Foley modification [25] was applied to determine the micropore distribution, with interaction parameters for N2 adsorbate taken from [24] and aluminosilicate adsorbent from [25].…”

“…This can be particularly challenging due to the wide variation of chemical and physical characteristics exhibited by commercial geopolymer precursors where a range of chemical reactivity is observed, Postprint of a paper published in Powder Technology, 29(2016): [17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33].

“…Nitrogen adsorption measurements were performed at 77 K. Surface areas were calculated according to theory as developed by Brunauer, Emmett, and Teller (BET) [26]. Micropore volume and surface area distributions were calculated according to Horvath-Kawazoe (H-K) theory [27]. The Barrett, Joyner, and Halenda (BJH) E281 method was used in determining the pore volume and surface area distributions for the mesopores.…”

Rigid Molecular Foams AbstractThis is the final report of a three-year, Laboratory Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). Organic analogues to inorganic zeolites would be a significant step forward in engineered porous materials and would provide advantages in range, selectivity, tailorability, and processing. Rigid molecular foams or "organic zeolites" would not be crystalline materials and could be tailored over a broader range of pore sizes and volumes. A novel process for preparing hypercrosslinked polymeric foams has been developed via a Friedel-Crafts polycondensation reaction. A series of rigid hypercrosslinked foams have been prepared using simple rigid polyaromatic hydrocarbons including benzene, biphenyl, m-terphenyl, diphenylmethane, and polystyrene, with dichloroxylene (DCX) as the crosslinking agent. Transparent gels are formed suggesting a very small pore size. After drying the foams are robust and rigid. Densities of the resulting foams can range from 0.15 g/cc to 0.75 g/cc. Nitrogen adsorption studies have shown that by judiciously selecting monomers and the crosslinking agent along with the level of crosslinking and the cure time of the resulting gel, the pore size, pore size distribution, and the total surface area of the foam can be tailored. Surface areas range from 160 to 1,200 m2/g with pore sizes ranging from 6 8, to 2,000 A.
