INTRODUCTION
Platinum and platinum-group metals (palladium, rhodium, ruthenium, osmium and iridium) are classified as noble metals, and as such have sought-after physical and chemical properties for both technical and decorative applications.
Noble metal coatings, produced by electrolysis in aqueous media, require mixtures of chemicals that are often harmful and sometimes toxic. Platinum group metals, for example, often require highly concentrated acids and bases to solubilize their oxidized forms.
