Water dissociation on multimetallic catalysts

Applied Catalysis B: Environmental, 2017
Abstract DFT based calculations were employed in the study of the dissociation of the water molecule onto copper and nickel (110) and (111) surface models, incorporating two additional metallic elements, because it was found previously that metal alloying leads to strong synergic effects in the catalysis of this reaction.

Dissociative chemisorption of water on titanium

Langmuir, 1988
Etude experimentale par spectrometrie de recul direct en temps de vol, et par spectrometrie de photoelectron. Analyse des especes presentes a la surface. L'analyse thermodynamique montre qu'il existe une force conductrice tres importante envers la chimisorption ...

Dissociation of Water on MgO(100)

The Journal of Physical Chemistry B, 2002
The adsorption of water on well-ordered MgO(100) surfaces has been studied using metastable impact electron spectroscopy (MIES), ultraviolet photoelectron spectroscopy (UPS), and temperature-progra...

Dissociation of water on a palladium nanoparticle

International Journal of Quantum Chemistry, 2010
AbstractAb initio SCF‐CI theory has been used to examine the interactions of a single water molecule with a 31‐atom nanocluster of palladium. Calculations are performed on singly‐charged cationic and anionic particles in addition to the neutral system to determine effects of charging on the adsorption energy of water and the barriers to dissociation ...

Partial Dissociation of Water on Ru(0001)

Science, 2002
Initial water deposition on the moderately reactive precious metal surface Ru(0001) has been thought to produce an ice-like bilayer. However, calculations from first principles show that the wetting layer observed on Ru(0001) cannot be formed of undissociated water molecules.

Dissociation of Acetic Acid in Water

Nature, 1933
IN the measurements of Maclnnes and Shedlovsky1 and Jeffery and Vogel2 on the conductivity of acetic acid and its salts in water, which have recently been the subject of correspondence in these columns3, the most noticeable divergence is in the values for dilute solutions of sodium acetate.

REACTIONS IN DISSOCIATED WATER VAPOR

Canadian Journal of Chemistry, 1951
Water vapor dissociated by an electric discharge and passed into a cold trap yielded products which gave off oxygen at temperatures above −120°C. and at room temperature consisted of hydrogen peroxide and water. With products formed under given conditions, the amount of oxygen evolved with warming was proportional to the total amount of product and ...

Thermoacoustics and thermal dissociation of water

The Journal of the Acoustical Society of America, 2007
Near 2600 K, 10% of water molecules are thermally dissociated at atmospheric pressure, with a reaction time constant below 1 ms. Such temperatures can be reached with focused sunlight. To use this endothermic reaction for the production of hydrogen, the hydrogen must be separated from the oxygen at high temperature, because they would quickly recombine

Dissociation of water by microwave radiation

Radiophysics and Quantum Electronics, 1994
The hydrogen-peroxide concentrations c(H2O2) in water irradiated by electromagnetic energy at frequencies of 2500 MHz and 10000 MHz are measured by means of chemiluminescence. It is concluded that water dissociation into H and OH groups is a part of the mechanism of microwave-radiation absorption.
