“…Using Equation (1) and substituting for the observed surface area As = 931 m 2 /g, we obtain a theoretical hydrogen uptake of 2.1 wt% in close agreement with the reported value of 2.3 wt%. Moreover, these capacities are consistent with the reported data for wide range of carbon-based materials with wide textural properties [26][27][28][29]. The density of the adsorbed hydrogen at 77 K can be calculated from the hydrogen uptake (2.3 wt%) and the volume occupied by hydrogen in the micropore volume (0.36 cm 3 /g).…”

Activated carbon has been synthesized from local palm shell, cardboard and plastics municipal waste in the Kingdom of Saudi Arabia. It exhibits a surface area of 930 m 2 /g and total pore volume of 0.42 cm 3 /g. This pristine activated carbon has been further anchored with nickel, palladium and platinum metal particles by ultrasound-assisted impregnation. Deposition of nanosized Pt particles as small as 3 nm has been achieved, while for Ni and Pd their size reaches 100 nm. The solid-gas hydrogenation properties of the pristine and metal-anchored activated carbon have been determined. The pristine material exhibits a reversible hydrogen storage capacity of 2.3 wt% at 77 K and 3 MPa which is higher than for the doped ones. In these materials, the spillover effect due to metal doping is of minor importance in enhancing the hydrogen uptake compared with the counter-effect of the additional mass of the metal particles and pore blocking on the carbon surface.

“…1 Storage capacities ranging from 0.25 to 20 wt % have been reported, 2 and numerous factors have been used to describe the variability and inconsistency of these results, including sample preparation, processing conditions, and presence of impurities such as amorphous carbon and catalyst particles. Both physisorption ͑H 2 -CNT van der Waals interactions͒ and chemisorption ͑formation of stable sp 3 C-H bonds͒ mechanisms have been accounted for hydrogen adsorption on CNTs.…”

An analytical model is presented to describe the effect of carbon nanotube (CNT) swelling upon hydrogenation on the hydrogen storage capacity of single-walled CNT bundles; the model is properly parameterized using atomistic calculations for the relationship between CNT swelling and the degree of hydrogenation as measured by the coverage of the CNTs by chemisorbed atomic H. The model generates experimentally testable hypotheses, which can be used to explain the lower H storage capacities reported for CNT bundles and the experimentally observed nonuniformity of hydrogenation of CNT bundles.

“…Carbon nanostructures are a potential cheap, abundant, and lightweight storage system that has become increasingly prominent in the last few decades. Initial work began with carbon nanotubes (CNTs) in the late 1990s and has since expanded to include a wide variety of sp 2 -hybridized carbon structures including graphene and spherical fullerenes [4][5][6][7][8]. Fullerenes have a theoretical maximum storage capacity of 58 hydrogen atoms in C60 (7.5 wt%) at 0 K. This produces a metastable structure with an internal pressure of 1.3 Mbar.…”

Full terms of use are available: http://www.bristol.ac.uk/pure/about/ebr-terms The study mainly focuses on H2 stored within the fullerene with some investigation into external H2. A significant attractive Cfullerene-H2 interaction energy of -28 kJ/mol is observed for H2 in curved carbon nanomaterials where H2 molecules are located ca. 2.9 Å from carbon atoms in a highly confined system. Dopants have the potential to increase the favourability of Cfullerene-H2interactions when multiple H2 molecules are present by affecting the orientation of H2 molecules within the carbon nanomaterial. This paper presents analysis of several carbon nanosystems and then proposes possible materials for H2 storage on board vehicles.2
