Abstract

Steady state voltammetry was used to study the oxidation of 0.02 mol dm3 borohydride ion (in 3 mol dm3 NaOH at 298 K) at three gold-based electrodes, namely: (a) a commercially available gold on Vulcan carbon Au/C, supported by carbon felt resulting in a 0.5 mg cm2 of Au loading, (b) gold nanoparticles deposited on titanate nanotubes with approximately 0.1 mg cm2 loading Au and (c) gold foil. Gold nanoparticles which are well dispersed onto titanate nanotubes can produce currents within the same order of magnitude as the Au/C and Au foil electrodes and represent an option for anode materials in a direct borohydride fuel cell.
