Electrochemical Oxidation of Borohydride on Cu Electrode
Advanced Materials Research, 2011The electrochemical behavior of BH4- on Cu electrode in 1M NaOH was investigated by cyclic voltammetry(CV) in the potential range of -1.2V to 0.4V versus Hg/HgO. The CV results show that Cu electrode has obvious catalytic activities to the BH4- hydrolysis which belongs to ‘catalytic’ electrode materials.

Nickel-Cerium Alloys for Borohydride Oxidation
ECS Transactions, 2013Nickel and nickel-cerium (Ni-Ce) alloys with different amounts of Ce (5 and 10 at.% Ce) have been prepared by arc melting and characterized by scanning electron microscopy and electron probe microanalysis based on energy dispersive X-ray spectroscopy, to investigate microstructure and to determine phase composition.

Tungsten oxide supported over mesoporous carbon rich in nitrogen was analysed for electrochemical oxidation of borohydride as a potential candidate for anodic catalyst in direct borohydride fuel cell. The fabrication of composite catalyst included a hard template method employing SBA-15 with optimal tungsten content.

Carbon supported palladium, gold and platinum nanoparticles were synthesized by microemulsion method in order to compare their catalytic activity for the electrooxidation of borohydride in alkaline medium. Two different pathways can be considered for this oxidation reaction: the direct oxidation of BH4- into BO2- and its indirect oxidation via hydrogen

Nanostructured Platinum-Copper Electrocatalysts for the Oxidation of Borohydride
ECS Transactions, 2013This 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

Chronopotentiometric Investigation of Borohydride Oxidation at a Gold Electrode
Journal of The Electrochemical Society, 2010Sodium 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 ...

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 ...
