Effective redox reactions by chromium oxide anions: Sulfur dioxide oxidation in the gas phase

International Journal of Mass Spectrometry, 2019
Abstract Unprecedented redox reactions of chromium oxide anions have been observed in the gas phase and investigated by mass spectrometric techniques and electronic structure calculations. The effective oxidizing and reducing power of chromium oxide anions is unravelled by sulfur dioxide: CrO4 − and CrO2 − generate CrO3 − as the reduction and ...

Radiation Induced Redox Reactions and Fragmentation of Constituent Ions in Ionic Liquids. 1. Anions

The Journal of Physical Chemistry B, 2011
Room temperature ionic liquids (IL) find increasing use for the replacement of organic solvents in practical applications, including their use in solar cells and electrolytes for metal deposition, and as extraction solvents for the reprocessing of spent nuclear fuel. The radiation stability of ILs is an important concern for some of these applications,

Influence of Anions on Electrochemical Redox Reactions and Electrical Properties using a Viologen Derivative

Japanese Journal of Applied Physics, 2006
Self-assembled monolayers of alkane derivatives with sulfur-containing head groups on gold substrates have been widely examined recently, since the binding between S atoms and the Au surface is strong. Viologen derivatives have been extensively investigated because of their well-known electrochemical behavior, including behavior as the electron ...

Uncovering the Structural Evolution in Na-Excess Layered Cathodes for Rational Use of an Anionic Redox Reaction

ACS Applied Materials & Interfaces, 2020
A new paradigm based on an anionic O2-/On- redox reaction has been highlighted in high-energy density cathode materials for sodium-ion batteries, achieving a high voltage (∼4.2 V vs Na/Na+) with a large anionic capacity during the first charge process. The structural variations during (de)intercalation are closely correlated with stable cyclability. To

Anti-siting for stabilizing structure and modulating cationic/anionic redox reactions

Energy Storage Materials
The layered Mn-rich oxide cathode materials with oxygen redox activity are highly appealing in sodium-ion (Na-ion) batteries because of their high energy density and low cost. However, the applications of such materials are hindered by issues such as low Mn redox potential and irreversible phase transformation.

Density-functional molecular-dynamics study of the redox reactions of two anionic, aqueous transition-metal complexes

The Journal of Chemical Physics, 2005
The thermochemistry of the RuO42−+MnO4−→RuO4−+MnO42− redox reaction in aqueous solution is studied by separate density-functional-based ab initio molecular-dynamics simulations of the component half reactions RuO42−→RuO4−+e− and MnO42−→MnO4−+e−. We compare the results of a recently developed grand-canonical method for the computation of oxidation free ...

Microgravimetric and laser beam deflection studies of redox reactions in polyantline at various concentrations of doping anions

Synthetic Metals, 1997
Abstract Quartz crystal microbalance and laser beam deflection techniques were used to study the role of ion exchange in electrochemical oxidation and reduction of polyaniline films synthesized in various acids. Mass changes and beam deflection angles were measured during voltammetric cycling of polyaniline in aqueous solutions containing H 4 SiW 12 ...
