Dissociation of Ozonide in Water [PDF]

open access: yesThe Journal of Physical Chemistry A, 2000
The free energy of bond dissociation for ozonide ion radical is found to be lowered in aqueous solution by about 20 kcal/mol relative to that in the gas phase, based on electronic structure calculations. Explicit treatment of anion−water clusters indicates that the stronger hydrogen bonds to first-shell water molecules formed by O- relative to O3 ...

Comparison of H2O Adsorption and Dissociation Behaviors on Rutile (110) and Anatase (101) Surfaces Based on ReaxFF Molecular Dynamics Simulation

open access: yesMolecules, 2023
The relationship between structure and reactivity plays a dominant role in water dissociation on the various TiO2 crystallines. To observe the adsorption and dissociation behavior of H2O, the reaction force field (ReaxFF) is used to investigate the ...

Improving the Stability, Selectivity, and Cell Voltage of a Bipolar Membrane Zero‐Gap Electrolyzer for Low‐Loss CO2 Reduction

open access: yesAdvanced Materials Interfaces, 2023
Electrolyzers for CO2 reduction containing bipolar membranes (BPM) are promising due to low loss of CO2 as carbonates and low product crossover, but improvements in product selectivity, stability, and cell voltage are required.

Dissociation chemistry of hydrogen halides in water [PDF]

open access: yesThe Journal of Chemical Physics, 2004
To understand the mechanism of aqueous acid dissociation, which plays a fundamental role in aqueous chemistry, the ionic dissociation of HX acids (X=F, Cl, Br, and I) in water clusters up to hexamer is examined using density functional theory and Møller–Plesset second-order perturbation methods (MP2).

Dissociation of Water on Defective Carbon Substrates [PDF]

open access: yesPhysical Review Letters, 2005
Using calculations from first principles, we found that water can dissociate over defective sites in graphene or nanotubes following many possible reaction pathways, some of which have activation barriers lower than half the value for the dissociation of bulk water. This reduction is caused by spin selection rules that allow the system to remain on the

Water Self‐Dissociation is Insensitive to Nanoscale Environments

open access: yesAngewandte Chemie, 2023
AbstractNanoconfinement effects on water dissociation and reactivity remain controversial, despite their importance to understand the aqueous chemistry at interfaces, pores, or aerosols. The pKw in confined environments has been assessed from experiments and simulations in a few specific cases, leading to dissimilar conclusions.
