Hydrogen storage in hybrid nanostructured carbon/palladium materials: Influence of particle size and surface chemistry

Hydrogen Storage in Pristine and d10-Block Metal-Anchored Activated Carbon Made from Local Wastes

“…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).…”

“…At room temperature and low pressure, Pd-anchored activated carbon has higher capacity than all other materials. This confirms the formation of palladium hydride at room temperature and low pressure, as demonstrated previously [28,29,32]. However, at high pressure, the favorable effect of palladium hydride formation is counteracted by the weight of the dopant, the filling of adsorbent micropores and pore blocking.…”

Improved hydrogen storage kinetics of nanocrystalline and amorphous Ce–Mg–Ni-based CeMg12-type alloys synthesized by mechanical milling

“…As a clean and available alternative energy, hydrogen power has become one of the most promising new energies owing to its highly stable, efficient and pollutionfree power. 2,3 Storage system is one of the main technical obstacles that limits the exploitation and utilization of hydrogen energy; to solve this major technical obstacle for realizing clean energy vehicles, developing a hydrogen storage system with excellent performance is a necessary prerequisite. 4 Metal hydrides with good performances are preferred as they meet the requirements of mobile applications.…”

An investigation on hydrogen storage thermodynamics and kinetics of Nd–Mg–Ni-based alloys synthesized by mechanical milling

“…The rapid development of automobile industry led to the excessive growth of fossil energy consumption and increasingly serious environmental problems, which has forced researchers in this area to find new and clean energy alternatives. Among available alternative energy sources, hydrogen energy is regarded as the most promising candidate owing to the characteristics of inexhaustible supply, zero-emission of green house gases and high energy efficiency [2,3]. A key technical obstacle for the realization of onboard fuel-cell or hydrogen fueled vehicles is to develop a practical hydrogen storage system [4].…”
