Hydrogen and Hydrogen-Storage Materials

2007
Currently, neutron applications in the field of hydrogen and hydrogen-storagematerials represent a large and promising research area, both from the fundamental and the applied points of view. In this chapter we review some relevant topics from this subject area, including hydrogen bulk properties (concerning both the solid and the liquid phases ...

Catalyzed Hydrogen Spillover for Hydrogen Storage

Journal of the American Chemical Society, 2009
A crucial bottleneck in developing a hydrogen economy is hydrogen storage. This is particularly true for transportation using hydrogen as the fuel for fuel cells. The U.S. Department of Energy has established specific R&D targets for on-board hydrogen storage.

Reactions of Hydrogen Atom with Hydrogen Peroxide

The Journal of Physical Chemistry A, 2007
Rate coefficients are calculated using canonical variational transition state theory with multidimensional tunneling (CVT/SCT) for the reactions H + H2O2 --> H2O + OH (1a) and H + H2O2 --> HO2 + H2 (1b). Reaction barrier heights are determined using two theoretical approaches: (i) comparison of parametrized rate coefficient calculations employing CVT ...

Hydrogen nanobubble at normal hydrogen electrode

Journal of Physics: Condensed Matter, 2013
Electrochemically formed hydrogen nanobubbles at a platinum rotating disk electrode (RDE) were detected by re-oxidation charge. The dissolution time course of the hydrogen nanobubbles was measured by AFM tapping topography under open-circuit conditions at stationary platinum and gold single-crystal electrodes.

Hydrogenation of polyaromatics in the presence of hydrogen-hydrogen sulphide system

Fuel, 1989
Abstract Thermal production of hydroaromatics by addition of molecular hydrogen to polyaromatics was studied in the presence of hydrogen sulphide or tetralin. The results indicate the importance of wall catalytic effects related to H 2 H 2 S activity during fossil fuel treatment.

Hydrogen–hydrogen bonding: The current density perspective

Journal of Computational Chemistry, 2015
Current density plots of closed‐shell intermolecular HH interactions characterized by a bond critical point (BCP) show two vortices separated by a saddle, a pattern which allows for a clear definition of a pair current strength. This HH current strength turns out to be roughly related to the potential energy density at the BCP and then to the ...

Photoreduction of hydrogen peroxide by hydrogen

The Journal of Physical Chemistry, 1976
The photoreduction of hydrogen peroxide in water under hydrogen of up to 100 atm pressure has been investigated. The reaction involves a chain mechanism with the quantum efficiency for the disappearance of hydrogen peroxide being strongly dependent upon the concentration of hydrogen peroxide. A maximum quantum efficiency of about 35 mol/einstein occurs
