Borohydride electro-oxidation in a molten alkali hydroxide eutectic mixture and a novel borohydride–periodate battery

Journal of Power Sources, 2015
Abstract The electrochemical oxidation of BH4− in a molten NaOH–KOH eutectic mixture (0.515:0.485 mole fractions), is investigated for the first time by cyclic voltammetry and electrochemical impedance spectroscopy. Anodically oxidized Ni is electrocatalytically more active than Pt for BH4− oxidation in the molten alkali electrolyte as shown by the ...

Nanostructured Platinum-Copper Electrocatalysts for the Oxidation of Borohydride

ECS Transactions, 2013
This work is focused on the use and study of the nanostructured platinum-copper catalysts deposited on the titanium surface by a two-step process which involves electroless copper deposition followed by a spontaneous Pt displacement from the hexachloro-complex solution as electrocatalysts for the oxidation of BH4 – ions in an alkaline

[116b] Borohydride reduction of periodate-oxidized chain ends

1968
Publisher Summary This chapter discusses the borohydride reduction of periodate-oxidized chain ends. Periodate-oxidized chain ends of RNA by reaction with 14C- or 3H-isoniazid or reduction with tritium borohydride. The borohydride method has the advantage that the label is introduced with minimal change in structure, thereby allowing the use of ...

Reduction of 4H-imidazole N-oxides with sodium borohydride

Chemistry of Heterocyclic Compounds, 1976
The reduction of derivatives of 4H-imidazole N-oxides with sodium borohydride leads, depending on the presence and position of an N-oxide group, to 1-hydroxyimidazoline or imidazolidine derivatives. Under the same conditions 4H-imidazole N,N′-dioxides form 1,3-dihydroxyimidazolidines. The reduction of 1-hydroxy-2,4,5,5-tetramethyl-3-imidazoline 3-oxide

Chemical Labeling of Carbohydrates by Oxidation and Sodium Borohydride Reduction

Current Protocols in Molecular Biology, 1994
AbstractThis unit describes a collection of methods for chemical labeling of carbohydrates (free oligosaccharides or oligosaccharides conjugated to proteins, peptides, or lipids) by oxidation followed by reduction or by direct reduction. Oligosaccharides can be labeled with either radioisotopes or nonradioactive fluorescent molecules.

Chronopotentiometric Investigation of Borohydride Oxidation at a Gold Electrode

Journal of The Electrochemical Society, 2010
Sodium borohydride (NaBH 4 ) presents interesting options for electrochemical power generation acting either as a hydrogen source or an anodic fuel for direct borohydride fuel cells. Though there have been several papers concerning electrochemical determination of relevant thermodynamic and kinetic parameters to the borohydride (BH 4 ) system, there ...

Reduction of quinoxaline-di-N-oxides with sodium borohydride

Tetrahedron, 1970
Abstract The reduction of a number of 2,3-disubstituted quinoxaline-di-N-oxides with sodium borohydride gave predominantly cis-2,3-disubstituted 1,2,3,4-tetrahydroquinoxalines in good yield. Treatment of the same quinoxaline-di-N-oxides with sodium dithionite gave the corresponding quinoxalines.

Metal Oxide Modified Lithium Borohydrides for Reversible Hydrogen Storage

MRS Proceedings, 2005
AbstractThe lithium borohydride has been modified by ball milling with metal oxides and metal chlorides as the additives. The modified lithium borohydrides released 9 wt% hydrogen starting from 473K. The dehydrided modified lithium borohydrides absorbed 7-9 wt% hydrogen at 873K and 7 MPa. The modification with additives reduced the dehydriding starting
