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 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.

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.

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

Dissociative Electron Capture in Water Vapor

Physical Review, 1961
An electron swarm experiment was conducted to study the process of negative-ion formation in water vapor by dissociative electron capture. Assuming that electrons are captiued in a single process at one well-defined energy, the present results are consistent with a beam experiment reported by Buchel'nikova. It was found that the capture cross section, (

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.

Water Dissociation on Magnetite (001) Films

The Journal of Physical Chemistry C, 2013
The interaction of water with Fe3O4(001) films has been studied by using Auger electron spectroscopy, low-energy electron diffraction, ultraviolet photoelectron spectroscopy, and high-resolution electron energy loss spectroscopy. The water molecules can be dissociated at temperatures below room temperature. The OH groups are not vertical to the surface

Partially Dissociated Water Dimers at the Water–Hematite Interface

ACS Energy Letters, 2019
The oxygen evolution reaction (OER) is thought to occur via a four-step mechanism with *O, *OH, and *OOH as adsorbed intermediates. Linear scaling of the *OH and **OOH adsorption energies is proposed to limit the oxides’ efficiency as OER catalysts, but the use of simple descriptors to screen candidate materials neglects potentially important water ...

Self consistent tight binding model for dissociable water

The Journal of Chemical Physics, 2012
We report results of development of a self consistent tight binding model for water. The model explicitly describes the electrons of the liquid self consistently, allows dissociation of the water and permits fast direct dynamics molecular dynamics calculations of the fluid properties.

Increased Acid Dissociation at the Quartz/Water Interface

The Journal of Physical Chemistry Letters, 2018
As shown by a quite significant amount of literature, acids at the water surface tend to be "less" acid, meaning that their associated form is favored over the conjugated base. What happens at the solid/liquid interface? In the case of the silica/water interface, we show how the acidity of adsorbed molecules can instead increase.
