Hydrogen nanobubble at normal hydrogen electrode
Journal of Physics: Condensed Matter, 2013Electrochemically 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, 1989Abstract 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, 2015Current density plots of closed‐shell intermolecular HH 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 HH 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, 2004C(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, 1982Abstract 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, 1984Abstract 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.

Photoreduction of hydrogen peroxide by hydrogen
The Journal of Physical Chemistry, 1976The 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

AbstractA selection of recent theoretical and experimental studies on electrolytic hydrogen evolution is presented. It is demonstrated with well‐defined model surfaces that this reaction is a very structure‐sensitive process. Crystallographic orientation, defect density and surface composition are parameters that determine the local geometric and ...
