“…After loading at 77 bar, a hydrogen storage of 1.38 wt.% was measured at room temperature. Other investigations of the hydrogen storage properties of GNFs reported that at room temperature and 80-100 bar the maximum hydrogen capacity was \0.2 wt.% [170,171]. These values are low and a long way from published DOE targets and hence GNFs do not seem to be suitable for on-board hydrogen storage.…”

“…Xu et al [171] experimentally measured hydrogen storage capacity of various carbon materials, including AC, single walled carbon nanohorn (a tubule with a cone cap, resembling a horn), SWNTs, and GNFs at 303 and 77 K. At room temperature the hydrogen capacity was \1%. At 77 K, the AC had maximum capacity of 5.7 wt.% at a pressure of 30 bar.…”

“…Carbon materials adsorb hydrogen gas through non-dissociative adsorption on the surface and hydrogen storage capacity is proportional to their specific surface area and the volume of micropores as shown in Fig. 27 [160,171,177,178]. The linear dependence of the storage capacity on specific surface area of carbon materials is independent of the nanostructure [160].…”

Hydrogen is gaining a great deal of attention as an energy carrier as well as an alternative fuel. However, in order to fully implement the so called 'hydrogen economy' significant technical challenges need to be overcome in the fields of production and storage of hydrogen and its point of use especially in fuel cells for the automotive industry. The purpose of this review is to present and discuss recent advances in the use of nanomaterials for solar hydrogen production and on-board solid state storage of hydrogen. The role of nanotechnology in enhancing the efficiency of fuel cells and reducing their cost is also discussed.

Resorcinol-formaldehyde (RF) hydrogel and RF-nickel-palladium (RF-Ni-Pd) hydrogel were synthesized by sol-gel polycondensation followed by ambient drying. Carbon gel and carbon-nickel-palladium doped gels were prepared by carbonizing the RF and RF-Ni-Pd gels at 900°C under a nitrogen atmosphere. The goal of this study was to determine the effect of oxidative thermal treatment on the electrochemical activity of nickel-palladium doped carbon gels (C-Ni-Pd). The scanning electron microscopy analysis, adsorption and X-ray diffraction measurements showed that the admixture of Ni and Pd to carbon matrix resulted in the modification of morphological, porous and crystalline features. It has been demonstrated that composite C-Ni-Pd composed of sphere-like granules incrusted with well-crystalline nickel and palladium particles exhibits electrochemical activity in 6 M KOH aqueous solution. Thermal treatment of the composite carried out in air at 450°C brought about the improvement of electrochemical activity in the potential range of the hydrogen sorption/desorption reaction.

“…The currently available technologies for hydrogen storage are gas compression, cryogenic liquefaction, intercalation in host metal, metal hydrides, and hydrogen physisorption. Many studies are focusing on improving present technologies and searching for advanced materials such as adsorbents [4]. Among them, carbonaceous materials are being investigated as potential hydrogen storage media because of their high specific surface area and large pore volume [5], and these carbonaceous materials include carbon nanotubes (CNTs) [6], carbon nanofibers (CNFs) [7,8], graphene [9,10], and traditional activated carbons (ACs) [11,12].…”
