Ti-Co mixed oxide as photocatalysts in the generation of hydrogen from water
(De Gruyter, 2022)
Black Sand-Based Photocatalyst for Hydrogen Production from EDTA Solutions Under UV–Vis Irradiation
Black sand from coastal deposits composed by a mixture containing oxides (Fe2O3, TiO2, SiO2, ZrO2, MnO, Al2O3, etc.) and metals (V, Cr, Ni, Sr, Ce, etc.). Both this mineral, as well as a fraction obtained from it, have ...
Investigation of the resonance-assisted hydrogen bond in model ß-diketones through localized molecular orbital analysis of the spin-spin coupling constants related to the O-H· · ·O hydrogen bond
(John Wiley & Sons Ltd, 2014-09)
The resonance-assisted hydrogen bond (HB) phenomenon has been studied theoretically by a localized molecular orbital (LMO) decomposition of the spin–spin coupling constants between atoms either involved or close to the ...
Neutral hydrogen versus proton-induced ionization in water vapor
(American Physical Society, 2019-10)
In the current work, we investigate the ionization of water molecules impacted by neutral hydrogen and proton beams. The continuum distorted wave-eikonal initial-state approximation is used to describe the reaction. ...
Comment on “Stark effect in neutral hydrogen by direct integration of the Hamiltonian in parabolic coordinates”
(American Physical Society, 2015-06)
We show that the resonances of the Stark effect in hydrogen reported by Fernández-Menchero and Summers [Phys. Rev. A 88, 022509 (2013)PLRAAN1050-294710.1103/PhysRevA.88.022509] are considerably less accurate than the number ...
Effect of LiCl presence on the hydrogen storage performance of the Mg(NH2)2-2LiH composite
(Royal Society of Chemistry, 2015-08-06)
The Mg(NH2)2-2LiH composite is a promising hydrogen storage material due to its favourable thermodynamics and hydrogen storage reversibility. However, its application is restricted owing to the presence of severe kinetic ...
Hydrogen production using mixed oxides TiO2-M (CoO and WO3)
(Facultad de Ingeniería (Seccional Bogotá), 2022)
Infrared spectroscopy of OH··CH3OH: Hydrogen-bonded intermediate along the hydrogen abstraction reaction path
(American Chemical Society, 2015-07)
Substantial non-Arrhenius behavior has been previously observed in the low temperature reaction between the hydroxyl radical and methanol. This behavior can be rationalized assuming the stabilization of an association ...
