Cyclic Voltammetry Characterization of Microparticle Monolayers

Structure analysis of layer-by-layer multilayer films of colloidal particles

“…Then, we have rinsed it with ultrapure water to remove polishing residues. After polishing, the gold surface roughness has been relatively small and we can assume that the surface is homogenous in the scale of the particle size [48].…”

Advanced Electroanalysis for Electrosynthesis

“…Cyclic voltammetry is the predominant electrochemical technique utilized, wherein a triangular waveform potential scan is applied to a working electrode to measure the resulting current (Figure A1). The ongoing oxidation and reduction reactions of electroactive species in a solution are facilitated by the process of potential cycling at the working electrode . As the applied potential on the working electrode approaches the equilibrium potential of the species in solution, there is a gradual increase in the response current and a corresponding decrease in the concentration of oxidized or reduced species on the electrode surface.…”

“…It has been observed that the adsorption strength increases with larger particle diameters and higher surface coverage. This insight provides valuable information regarding the deposition of different particles onto surfaces . The characterization of the synthesized Pt–Ru catalysts and their catalytic activities in relation to fuel cells has been conducted using CV .…”

“…The ongoing oxidation and reduction reactions of electroactive species in a solution are facilitated by the process of potential cycling at the working electrode. 97 As the applied potential on the working electrode approaches the equilibrium potential of the species in solution, there is a gradual increase in the response current and a corresponding decrease in the concentration of oxidized or reduced species on the electrode surface. A peak corresponding to oxidation or reduction is observed until the equilibrium is reached between the charge transfer and diffusion processes.…”

Cyclic Voltammetry and Its Applications

“…CV can also be used in tracing activated iridium oxide film (AIROF) microelectrode via the variation of scan rate during the steps of fabrications and animal implantation [26]. In particular, CV from gold rotating disk electrode (Au RDE) has also been proved to be useful in determining surface coverage of silica microparticle monolayer and revealing that the adsorption is stronger with increasing diameter and surface coverage, which sheds the light on the deposition of a variety of particles onto the surface [27]. In terms of fuel cells, CV has been used to characterize the synthesized Pt-Ru catalysts and their catalytic activities [28].…”
