Activated carbons (ACs) from biomass sources have attracted attention due to their superior properties including, easy preparation, abundant raw materials, ready availability, low cost, low mass density, high specific surface area and micropore volume, fast and reversible kinetics, structural diversity, and sustainable regeneration. Due to their tunable aspects, bio‐derived ACs are among the most...
In presented experimental study, the single-walled carbon nanotube bundles were irradiated by 60Co γ - quanta with energies 1.2 MeV in hydrogen and deuterium media at room temperature. Investigation of hydrogen sorption/desorption was carried out for irradiated and unirradiated samples in wide temperature range from 12 to 1273 K. Comparison of obtained results denotes that hydrogen adsorption capacity...
The characteristics of hydrogen adsorption on Li metal atoms dispersed on graphene with boron substitution were investigated for Li clustering, hydrogen bonding characteristics and open metal states of Li adatom by using density functional theory calculations. It is found that Li atoms are well dispersed on boron substituted graphene and can form the (2 ?? 2) pattern because clustering of Li atoms...
Magnesium hydride ball milled nanocomposites was prepared separately using vibratory and planetary ball milling devices under argon atmosphere, mixing with 5%wt. Fe and FeF3 to improve the kinetics of H-sorption without reducing the high hydrogen storage capacity. Morphology, structural and thermal characterization of the MgH2 composites was performed using XRD, SEM and simultaneous TG and DSC techniques...
