What is Platinum Electroplating Baths about?
The document discusses studies of platinum electroplating baths derived from Pt(NO2)4 in aqueous methanesulphonic acid. When Pt(NO2)4 is dissolved in the acid, the nitrite ligands are displaced by water ligands over time and with increased temperature or acid concentration. A solution containing the species Pt(NO2)(H2O)3+ as the dominant form provides the basis for a reasonable plating bath, allowing deposition at 343K and current densities from 1-15mA/cm2, though with low efficiencies around 10-15%.
