The fabrication of semiconductor products for the microelectronic industry requires the deposition of thin noble metal layers (e.g. Au-Sn and Pd) by means of processes involving fluid baths that contain metal ions (e.g. electrowinning and electroless plating). After several cycles, the plating solutions are used up and must be replaced, generating large volumes of discarded solutions containing precious metals. The metals (Au and Pd) are recovered either by electrowinning, a slow batch process, or by the use of toxic molecules (e.g. cyanides). This study demonstrates the possibility of using an atmospheric plasma technology to recover Au and Pd from these solutions, which provides a faster and greener process. Plasma discharges are generated at the surface of the solutions, causing ions to precipitate as nanoparticles. The treatment (few minutes only) allows the recovery of >95% gold, and >60% palladium.The process separates Au (NPs) from Sn ions (remaining in solution), as confirmed by elemental analysis and XPS. Particle size distributions of the nanoparticles recovered through the process suggests that as-

“…In the past few years, the development of devices and generators enabling sustained plasma discharges at atmospheric pressure conditions has broadened the spectra of potential applications. More precisely, dielectric barrier discharge (DBD) reactors figure as one of the strategies for efficiently expanding the size of plasma, and their coverage on both solid or liquid surfaces . Recently, our team reported a new bench‐top DBD plasma reactor allowing the synthesis of metal nanoparticles .…”

Atmospheric-pressure plasmas produced by dielectric barrier discharge can be used to grow nanoparticles from aqueous solutions containing ions from the platinum group metals (PGM: Pt, Pd, and Rh). The technology could also be applied to recover PGM from waste solutions. In plasma electrochemistry, PGM solutions act as a liquid electrode, and a counter electrode located near the surface of the liquid is used to generate the plasma (e.g., hydrogen, argon). The treatment synthesizes nanoparticles within minutes, which can be separated from the treated solutions. In the present study, small concentrations of PGM ions (1 × 10 −3 m) are recuperated from aqueous solutions containing chloride ions. The efficiency of the process is quantified by elemental analysis, and the size of the colloids, measured by dynamic light scattering (DLS) and transmission electron microscopy (TEM). Very high recovery yields are found for palladium (>99%), as well as for rhodium (>75%) and for platinum (>51%). Plasma electrochemistry is a very efficient and rapid process to recuperate PGM ions from water solutions (faster than conventional electrowinning) such as industrial waste, acid leach, and related effluents. The very fine and surfactant-free nanoparticles could find promising applications as industrial and automotive catalysts. Nanoparticle Plasma Synthesis

The investigation of Dielectric Barrier Discharges (DBD) in the absence of breakdown has significance in the perspective of the technological processes based on discharge phenomena and high voltage techniques. This study carries out transient analyses for the temporal evolution of electrical field, space charge density, polarization current while charging experimental Metal-Gas-Dielectric-Metal (MGDM) DBD cell. For these proposes, a theoretical model based on current continuity and two-layer polarization mechanism is developed for the investigation of an experimental MGDM electrodes system. In the steady state, the model obeys energy conservation law. Analysis results are discussed on the basis of experimental current measurements to explain pulsed DBD current.
