Electrochemical studies of gold and chloride in ionic liquids

Ionic liquid assisted one step green synthesis of Au–Ag bimetallic nanoparticles

“…During the continuous cycling process, the growth of reduction peaks at -0.17, -0.81, and -0.50 V [peak 1(b)] confirms the electro deposition of Au-Ag bimetallic nanoparticles on the ITO glass surface. Further, the oxidation peaks around 0.12 and 0.58 V indicate the oxidation of chloride to chlorine [36,37]. Based on previous literature reports, the expected mechanism for the formation of Au (0) and Ag (0) electrodeposition processes are as follows [36][37][38]:…”

Analysis of water in room temperature ionic liquids by linear sweep, differential pulse and square wave cathodic stripping voltammetries

“…In this paper, the oxide state related to this signal will be labeled as OC1, according to the notation used by Angerstein-Kozlowska et al [42]. The gold oxide formation in RTILs is conditioned to the presence of residual water, and it has shown its deleterious influence on the electrodissolution of gold films in [C 4 mim][NTf 2 ], since the oxidation efficiency is less than 100% [43]. Fig.1 shows cyclic voltammograms of gold electrodes in four of the RTILs used in this study.…”

Combining thermogalvanic corrosion and thermogalvanic redox couples for improved electrochemical waste heat harvesting

“…Future work will focus upon flow systems, to provide a constant electrolyte composition in contact with a corroding electrode. There is even the possibility to use halides as catalytic mediators for the dissolution of certain metals, the halide dissolving metals without being bound in subsequent complexes [24].…”
