“…The median cylindrical pore diameter based on the Horvath-Kawazoe method [21,22] was 8.9 Å. The specific surface area is relatively high because the crystal is porous, but is lower than that of MOFs designed to have a high specific area [23][24][25][26].…”

Abstract:We attempted synthesis of the hydrogen adsorption material suitable for the fuel cell vehicles (FCEVs). The designed and synthesized Cu 2 (3,5-Pyridinedicarboxylate) 2 (=Cu 2 PDC 2 ) metal complex showed an extremely high volumetric uptake density for a physisorption material, even though the specific surface area was only about 1,000 m 2 g −1 . Factors for high uptake properties are considered to be the increased adsorption sites per unit area, the increased adsorption energy, and the optimized design of pore shapes. High hydrogen uptake on volumetric basis is especially effective for FCEV because the tank volume is reduced. It is expected that property prediction using computational simulation and sophisticated analysis at the micro and nano levels will become an indispensable tool in the design of functional materials.

“…The micropore volume, V , was determined with the Dubinin-Radushkevich equation [23], and the mesopore volume, V m , was calculated as the difference between V T and V . The pore diameter, D p , was calculated using the ratio 4 V T /S BET , and the pore size distribution, by the HK method [24].…”

“…Low pressure CO 2 sorption/desorption data was used to calculate the PSD using the Horvath-Kawazoe method (Dombrowski et al, 2001). The differential PSD profiles in the micro-porous region for the three samples are shown in Fig.…”
