Electrodeposition of Bismuth From Nitric Acid Electrolyte



E Sandnes, Maureen E. Williams, Ugo Bertocci, Mark D. Vaudin, Gery R. Stafford


The electrodeposition of Bi from acidic nitrate solution was examined. Bismuth deposition was determined to be quasi-reversible on Au, with a current efficiency of 100%, based on integration of deposition and stripping voltammetric waves. No interference from nitrate reduction was found on Bi and Au, whereas nitrate reduction occurred on W and Cu electrodes. Analysis of current-time transients clearly shows nucleation on Au to be instantaneous. Field emission SEM revealed nodular deposits with moderate surface roughness. Nodule size varied from 1 micron to 5 microns depending on deposition potential and deposit thickness. X-ray diffraction patterns for all deposits were indexed to rhombohedral bismuth. The deposits showed fairly strong {01-12} crystallographic texture at high deposition overpotentials.
