Redox properties of polyoxometalates: new insights on the anion charge effect

Dalton Trans., 2006
In this paper we study the electronic structure of Lindqvist, Keggin, Dawson and Preyssler polyoxometalates (POMs) at the DFT level, particularly their LUMOs and reduction energies. Our aim was to revisit the previously reported evidence that a linear relationship exists between reduction potentials and molecular charges in Keggin anions.

Optimized Anion Exchange Membranes for Vanadium Redox Flow Batteries

ACS Applied Materials & Interfaces, 2013
In order to understand the properties of low vanadium permeability anion exchange membranes for vanadium redox flow batteries (VRFBs), quaternary ammonium functionalized Radel (QA-Radel) membranes with three ion exchange capacities (IECs) from 1.7 to 2.4 mequiv g(-1) were synthesized and 55-60 μm thick membrane samples were evaluated for their ...

A Class of Sodium Transition‐Metal Sulfide Cathodes With Anion Redox

Advanced Materials
AbstractSodium‐ion batteries (SIBs) are entering commercial relevance as a sustainable and low‐cost alternative to lithium‐ion batteries. Improving the energy density of SIBs is critical to enable their widespread adoption. Here, a new class of cathode materials Na6MS4 (M = Co, Mn, Fe, and Zn) that exhibit high charge‐storage capacity is reported ...

[Effect of bicarbonate and certain anions on NADP redox].

Ukrainskii biokhimicheskii zhurnal (1978), 1980
The paper deals with the intensity of NADPH formation in the isocytrate dehydrogenase reaction and NADPH oxidation in the lactate and malate dehydrogenase reactions. It is shown that bicarbonate, phosphate, acetate, chloride and triethanolamine buffer in concentrations of 1 . 10(-1) = 4 . 10(-1) M can inhibit these processes intensity.

Redox chemistry of Perrhenate and other anions

2018
This thesis discusses reduction and oxidation reactions catalysed by the perrhenate anion and oxidation reactions catalysed by other oxo-anions i.e. sulfate and nitrate. Chapter one introduces catalytic hydrosilylation, hydroboration, deoxydehydration and alkene epoxidation and some of their applications, with a focus on high oxidation state complexes.
