Electrocatalysts for the anodic oxidation of borohydrides

Electrochimica Acta, 2004
Anodic performances of alkali borohydrides on several electrocatalysts such as Ni, Raney Ni, Pd, Pt, Cu, Au have been studied in an effort to develop suitable electrode materials for a borohydride-fueled fuel cell. The open-circuit potentials (OCPs), polarization performances, and hydrogen evolution behaviors were examined in a three-electrode system ...

Metallocomplex-based borohydride electro-oxidation catalysts

Catalysis Today, 2011
Abstract We have found that certain kind of complexes on carbon black catalyze borohydride electro-oxidation. All of the Rh porphyrins tested in this study exhibited high activity regardless of the structure of the porphyrin ligands. While other metalloporphyrins also catalyzed borohydride electro-oxidation, the activities were much lower than those ...

Nickel-Cerium Alloys for Borohydride Oxidation

ECS Transactions, 2013
Nickel 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.

Reduction of graphene oxide with substituted borohydrides

J. Mater. Chem. A, 2013
The emergence of graphene as a next-generation material promises enhanced improvement in various fields of materials science. So far, the oxidation of graphite to graphite oxide and consequent reduction to chemically reduced graphene oxide is the most relevant method towards large scale production of graphene materials.

Electrochemical Oxidation of Borohydride on Cu Electrode

Advanced Materials Research, 2011
The 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.

A mechanistic study of borohydride anodic oxidation

Catalysis Today, 2011
Abstract In direct borohydride fuel cells, the anodic oxidation of borohydride is often accompanied by hydrogen evolution which decreases the number of electrons released to the external circuit from each borohydride ion and thus lowers the Faradaic efficiency and causes safety problems.

Electrocatalytic Borohydride Oxidation by Supported Tungsten Oxide Nanoclusters Towards Direct Borohydride Fuel Cells

2017
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.

PtNi-Decorated Metal Oxide Electrodes for Borohydride Fuel Cells

ECS Transactions, 2016
PtNi nanoparticles are grafted onto three different metal oxide supports, namely MnO2, MnO2+TiO2 and MnO2+NiO. Subsequently, their activity for oxygen reduction reaction (ORR) and borohydride oxidation reaction (BOR) in alkaline media was studied using voltammetric techniques.
