Molecular hydrogen is packed extremely densely, with about twice the density of liquid hydrogen (144gHper litre of pore volume). We found a penta-dihydrogen cluster where Hmolecules in one position have rotational freedom, whereas Hmolecules in another position have a well-defined orientation and...
The mechanisms of these various insertions are discussed in terms of the degree of hydridic nature of the hydridic hydrogen in the initial iron complexes... M Chen,S Zhu,F Wang - 《Journal of the American Ceramic Society》 被引量: 40发表: 2010年 ...
The cationic cluster complex [Ru 3 ( μ 3 -ampy( CO ) 10 ][BF 4 ] ( 1 ) (Hampy = 2-amino-6-methylpyridine) reacts with hydrogen at room temperature undergoing an oxidative substitution of CO to give the cationic dihydrido derivative [Ru 3 ( μ -H) 2 ( μ 3 -ampy)(CO) ...
Solution 1H NMR, NOE, and T1 relaxation measurements of [K(1,10-diaza-18-crown-6)][ReH6(PPh3)2] indicate that these interactions also persist in toluene solutions of this compound.Key words: rhenium, hydride, phosphine, hydrogen bonding, self-assembly....
Various set of compounds are studied having different ratio of protic and hydridic hydrogens. Moreover, protic–hydridic based chemical additives (NH3, BH3 and NH3BH3) are added to protic–hydridic based hydrogen storage compounds to increase their hydrogen gravimetric density. Our study shows ...

A comprehensive survey of achievements in electrocatalysis for the hydrogen evolution reaction (h.e.r.) has been reviewed with the main emphasis on the composite d-metal catalysts. The basic concept of the Brewer—Engel valence-bond theory that relates the electronic state of highest multiplicity ...
Electrocatalytic and Hydridic Theory for Hydrogen Electrode Reactions and Prediction of Synergetic Catalysts in the Light of Fermi Dynamics and Structural Bonding FactorsThe Balandin type volcano plots have been considered for the main criterion both in catalysis and electrocatalysis to estimate their ...
Several other hypo-hyper-d-electronic combinations of transition metals (Mo-Go, Mo-Ni, Zr-Ni, W-Pt) have also been thoroughly investigated along their phase diagrams as electrode materials for the hydrogen evolution reaction (HER). It has been inferred that each hypo-hyper-d-electronic ...
