Abstract

By means of X-ray diffraction, the phase composition of electrolytic deposits obtained during simultaneous electrodeposition of platinum with lead, and of platinum with mercury, on glassy carbon was investigated. Formation of dispersed platinum (D≈65-110 Å) in both binary system cases, of a solid solution of platinum-lead and of the intermetallic compound PtHg 4 was proved. During the anodic scan up to a potential of +0.75 V in 0.1 M HCl, the compound PtHg 4 undergoes partial oxidation; electrolytic platinum is resistant to oxidation under these conditions.
