Resumen:
This work aims to define general criteria to allow theoretical and experimental design ofnew materials with high hydrogen content, with a view to their potential application asmoderators in reactors at high temperatures and hydrogen storage materials.To this end we study the effects of nickel impurities on the properties of pure carbon(slabs as well as nanoparticles and gels) in order to analyze the thermodynamicalcharacteristics, and improve the behavior of alloys for Ni-metal hydride rechargeablebatteries. These elements are chosen because they have a wide range of solubility ofhydrogen, which from the technological point of view makes them important candidatesin the search for new materials. Our results show that this kind of carbon material couldbe used as support for hydrogen storage improving the screening charge density and thedensity of available states, as analyzed by the authors in previous works.1.
