“…2− and H 2 evolution has been noted previously. 52,53 Third, the presented data clearly indicate the production of materials with metallic bonding involving Pd atoms, strongly implicating a reduction process occurred. There was no indication of residual Pd cyanide salts in the X-ray diffraction or in Raman spectra (data not shown).…”

Electrodeposition of Pd from alkaline baths containing Pd(CN)2 and KCN with liquid metal electrodes has been performed. Data are presented that Pd dissolved into and reacted with the liquid metal electrodes via an electrochemical liquid-liquid-solid (ec-LLS) process. HgPd crystals were obtained with liquid Hg electrodes. On solid In electrodes, In7Pd3 was exclusively formed. In contrast, InPd was the primary product with Hg1-xInx alloy electrodes. X-ray diffraction, scanning electron microscopy, and electron backscattering diffraction show that the materials were not a pure phase, as minor components of HgPd and In7Pd3 were observed for various liquid Hg-In compositions. A mechanism is proposed where the InPd intermetallic forms through an intermediate phase of HgPd by the substitution of In atoms for the Hg sites of the unit cell. This study thus motivates further exploration of Hg1-xInx as a versatile medium for intermetallic synthesis by ec-LLS.

“…The electrodeposition of palladium metal has been known since the nineteenth century [82], but its use became common only in the 1980s, when new legislative measures banished nickel from objects intended for use in prolonged contact with the skin. Palladium is used both as a final coating and as an intermediate layer to improve corrosion resistance, increase the adhesion of subsequent precious deposits, and to act as a diffusion barrier layer [83].…”

Electroplating processes are widely employed in industrial environments for a large variety of metallic coatings, ranging from technological to decorative applications. Even if the galvanic electrodeposition is certainly a mature technology, new concepts, novel applications, environmental legislation and the new material requirements for next-generation devices make the scientific research in this field still very active. This review focuses mostly at the decorative and wearable applications, and aims to create a bridge between the past knowledge and the future direction that this process, i.e., electrodeposition, is taking. Both the theoretical fundamentals as well as some of the most widespread practical applications-limited to metallic and alloy coatings-are explored. As an integral part of the industrial process, we take a look at the main techniques thought which the quality control of deposits and surfaces is carried out. Finally, global industrial performance and research directions towards sustainable solutions are highlighted.
