Nanospace-engineered carbons for reversible storage of natural gas and hydrogen حسب Romanos, J.

"…Langmuir and Ono-Kondo analysis of CH4 excess isotherms at 295 K gives surface area (2400-2700 m2/g, agree with BET area), film thickness (~0.4 nm), saturated film density (320-440 g/cm3), and average binding energy (8-9 kJ/mol). 6.Briquetting can increase volumetric storage capacity by factor of 2 if surface area remains constant.…"

Open carbon frameworks - a search for optimal geometry for hydrogen storage حسب Kuchta, Bogdan

"…From an analysis of an analytical model and simulations of adsorption the physical limits of hydrogen adsorption have been defined: (i) higher storage capacities in slit-shaped pores can be obtained by fragmentation/truncation of graphene sheets into nano-metric elements which creates surface areas in excess of 2600 m2/g, the surface area for infinite graphene sheets; (ii) the positive influence of increasing surface area is compensated by the decreasing energy of adsorption in the carbon scaffolds of nano-metric sizes; (iii) for open carbon frameworks (OCF) built from coronene and benzene molecules with surface areas 6500 m2 g-1, we find an impressive excess adsorption of 75–110 g H2/kg C at 77 K, and high storage capacity of 110–150 g H2/kg C at 77 K and 100 bar; (iv) the new OCF, if synthesized and optimized, could lead to required hydrogen storage capacity for mobile applications.…"
