Characterization of Nanocomposites for Hydrogen Storage
(Amer Inst Physics, 2017)
The use of hydrogen as an energy carrier suitable to replace gasoline and other fossil fuels has been widely discussed as a way to sustainably fuel our civilization. However, hydrogen storage is a major harrier in the ...
MATERIALS FOR HYDROGEN STORAGE IN NANOCAVITIES: DESIGN CRITERIA
(International Journal Of Hydrogen Energy, 2013-01-16)
Improvement of Hydrogen Vacancy Diffusion Kinetics in MgH2 by Niobium- and Zirconium-Doping for Hydrogen Storage Applications
(American Chemical Society, 2016-03)
Transition metal (TM) catalytic dopants are broadly used in hydrogen storage materials to increase H2 desorption and absorption kinetics. We have studied H vacancy formation energy in pure, Nb- or Zr- doped bulk magnesium ...
Hydrogen divacancy diffusion: A new perspective on H migration in MgH2 materials for energy storage
(Royal Society of Chemistry, 2016-12-05)
The formation and diffusion of pairs of hydrogen vacancies (divacancies) in magnesium hydride is modeled using density functional theory. Compared to the commonly studied case of single hydrogen vacancies, it is found that ...
Polymer Nanocomposites for Hydrogen Storage
(Amer Inst Physics, 2017)
Hydrogen is considered to be a clean, economical and safe renewable energy source that would be ideal to replace fossil fuels, because it is light, highly abundant and its oxidation product (water) is environmentally benign. ...
Tetrahydroborates: Development and Potential as Hydrogen Storage Medium
(Multidisciplinary Digital Publishing Institute MDPI, 2017-10-31)
The use of fossil fuels as an energy supply becomes increasingly problematic from the point of view of both environmental emissions and energy sustainability. As an alternative, hydrogen is widely regarded as a key element ...
DFT study of the hydrogen adsorption and storage on Ni4 cluster embedded in multivacancy graphene
(Elsevier, 2020-11-06)
Hydrogen adsorption stability, geometry, electronic structure and mechanism has been investigated on Ni4 cluster embedded in graphene with three, four and six vacancies by density functional theory (DFT) calculations. An ...
Electrode surface modifications improve cathode hydrogen production and anode capacity in Ni-MH batteries
(Elsevier B.V., 2006-02-01)
This paper reports results from electrochemical evaluations of electrodes used as cathodes for a hydrogen evolution reaction and anodes in Ni-MH batteries that had been surface-modified by micro-encapsulation, co-deposition ...
