A New Publication Combined EQCM and Probe Beam Deflection in Deep Eutectic Solvents Available for Download
Summary
Here they explore the use of the combined EQCM/PBD technique to the study of Ag and Sn electrodeposition from a DES comprising a 1:2 mixture of choline chloride and ethylene glycol.The problem can be overcome by operating at scan rates 1-2 orders of magnitude slower, permitting application of this powerful technique to novel media of technological interest.Collaborators on this project include: A. Robert Hillman, Karl S. Ryder, Christopher J. Zaleski, Virginia Ferreira, Christopher A. Beasley, and Eric Vieil.Following are some highlights of the publication:· The EQCM/PBD method has for the first time been applied to metal deposition/dissolution processes in deep eutectic solvents· The PBD responds to solution phase chemistry, while the E and QCM probes respond to interfacial processes only· The combination of electrochemical (E), gravimetric (QCM) and optical (PBD) responses provides diagnostic capability· EQCM/PBD data reveal the influence of Ag/Cl− complex speciation in the high chloride concentration ionic liquid· The PBD response reveals the intrusion of solubility limitations into Sn anodic strippingAbstractThe electrochemical quartz crystal microbalance (EQCM) and probe beam deflection (PBD) have been widely used to study interfacial processes in molecular solvent-based electrolytes.Here they explore the use of the combined EQCM/PBD technique to the study of Ag and Sn electrodeposition from a DES comprising a 1:2 mixture of choline chloride and ethylene glycol.The problem can be overcome by operating at scan rates 1-2 orders of magnitude slower, permitting application of this powerful technique to novel media of technological interest.
