Enhanced hydrogen storage in Ni/Ce composite oxides

Enhanced hydrogen storage in Ni/Ce composite oxides.

The properties of dried (but not calcined) coprecipitated nickel ceria systems have been investigated in terms of their hydrogen emission characteristics following activation in hydrogen. XRD and BET data obtained on the powders show similarities to calcined ceria but it is likely that the majority of the material produced by the coprecipitation process is largely of an amorphous nature. XPS da...

Composite Hydrogen Storage Cylinders

Electric field enhanced hydrogen storage on polarizable materials substrates.

Using density functional theory, we show that an applied electric field can substantially improve the hydrogen storage properties of polarizable substrates. This new concept is demonstrated by adsorbing a layer of hydrogen molecules on a number of nanomaterials. When one layer of H(2) molecules is adsorbed on a BN sheet, the binding energy per H(2) molecule increases from 0.03 eV/H(2) in the fi...

Hydrogen storage in carbon nanotubes with Ni nanoparticles by electrochemical

In this paper, the electrochemical hydrogen storage in nanocomposite materials was studied. Multi-Walled Carbon Nanotubes (MWCNTs) electrode was prepared by mixing with special composite. The optimum ratio of MWCNTs was estimated 30-70% (w/w) in the composite material. MWCNTs were synthesized by Chemical vapor deposition (CVD). The nanocomposite was homogenized by microwave. Cyclic voltammetry ...
