✦ Synopsis

This paper reviews the chemical and electrochemical depositions of platinum group metals (PGMs) from aqueous solutions. With a brief introduction on the fundamental aspects of chemical/electrochemical depositions, the review describes recent advances in chemical and Abbreviations: CD, cathode current density expressed as amperes per cm 2 ; CE, cathode current efficiency; dc, direct current; DMFC, direct methanol fuel cell; DNS, dinitrosulfatoplatinate; Electroforming, deposition of thick metallic coating which is later removed from cathode substrate, used for preparing thick metallic foils, halograms, duplicating complicated structures etc.; NHE, normal hydrogen electrode; PCB, printed circuit board; PGM, platinum group metal; PEMFC, polymer electrolyte membrane fuel cell; PET, polyethylene terphthalate; Pt-P-salt, cis-diammineplatinum(II)nitrite; PWB, printed wiring board; Strike, very thin metallic coating that is given prior to the main PGM coating for changing the character of base metal; SCE, saturated calomel electrode
