摘要: Hydrogen adsorption measurements on different metal−organic frameworks (MOFs) over the 0−60 bar range at 50 and 77 K are presented. The results discussed with respect to materials’ surface area thermodynamic properties of adsorbed phase. A nearly linear correlation between maximum hydrogen excess amount Brunauer−Emmett−Teller (BET) was evidenced both temperatures. Such a trend suggests that phase materials is similar in nature. This interpretation supported by near saturation K. In particular it found consistently exhibits liquid state despite significant structural chemical differences tested adsorbents. behavior viewed as consequence molecular confinement nanoscale pores. variability relating could be explained dif...
