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 ...

Hydrogen storage on fullerenes: hydrogenation of C59N? using C60H36 as the source of hydrogen

Chemical Communications, 2004
C(60)H(36) has been used as the source of hydrogen for the in situ hydrogenation of (C(59)N)(2), leading to C(59)NH(5) as the main reaction product identified by negative-ion mass spectrometry and providing evidence of the usage of C(60) as a storage device for hydrogen.

Hydrogenation by hydrogen bronzes I. Hydrogenation of ethylene by HxMoO3

Journal of Catalysis, 1982
Abstract Hydrogenation of ethylene has been studied on hydrogen molybdenum oxide bronzes prepared by spillover of hydrogen from supported Pt particles. The temperature of the formation and of the outgassing of the bronze, as well as the Pt content, was found to influence the rate of the reaction of ethylene.

Hydrogenation by hydrogen bronzes II. Hydrogenation of ethylene by HxV2O5

Journal of Catalysis, 1984
Abstract Hydrogen vanadium oxide bronzes have been prepared by spillover of hydrogen from supported Pt particles. The crystallinity of the starting oxide disappears progressively during the insertion of hydrogen so that a bronze with an initial stoichiometry of about H 3.3 V 2 O 5 is quasi-amorphous.
