Electrodeposition of Gold on Fluorine-Doped Tin Oxide: Characterization and Application for Catalytic Oxidation of Nitrite

“…[13][14][15] Although various self-assembly approaches have been applied to the deposition of gold nanostructures on TCOs, they usually require special organic binders such as (aminopropyl)siloxane, (mercaptopropyl)siloxane, 16 which often deteriorate the catalytic activity and conductivity of Au deposits. Meanwhile there were many reports on the electrodeposition of Au directly on ITO in an aqueous phase, [17][18][19] it was hardly found on FTO even though the latter is more useful in many cases where higher thermal and chemical stabilities are required. Sheridan et al directly electrodeposited Au nanoparticles on FTO and 3-aminopropyldimethylmethoxysilane (ADMMS)-modified FTO in an aqueous phase with an emphasis on the control of nucleation mechanism, 20 while the potential application to sensing devices were left for further study.…”

Anisotropic In-Plane Conductivity and Dichroic Gold Plasmon Resonance in Plasma-Assisted ITO Thin Films e-Beam-Evaporated at Oblique Angles

“…For these two orientations, the spectra of the evaporated ITO films depict a similar absorption band at 535 nm attributed to the surface plasmon resonance of the electrochemically deposited gold nanoparticles. 49,50,63,64 Conversely, in the plasma assisted film, azimuthally turning the sample leads to significant changes in the absorption spectra. At 0º, the spectrum is characterized by a well defined resonance peak at 520 nm, while at 90º it depicts a less resolved structure where would imply an increase in this parameter to a value close to one.…”

“…49,50,61,62 Herein, we propose to exploit the bundling surface and conductivity anisotropies of the plasma assisted OAD thin films for the development of dichroic thin films. In previous works on plasmon anticounterfeiting films we proposed the use of OAD SiO 2 thin films as hosts or templates for, respectively, the fabrication of embedded anisotropic gold nanoparticles 50 or Ag surface nanostrips after evaporation and laser treatment.…”

“…In previous works on plasmon anticounterfeiting films we proposed the use of OAD SiO 2 thin films as hosts or templates for, respectively, the fabrication of embedded anisotropic gold nanoparticles 50 or Ag surface nanostrips after evaporation and laser treatment. 49 The strategy proposed here consists of using the plasma assisted OAD ITO films as electrodes to directly deposit Au nanostructures with surface plasmon resonance activity.…”

Electrochemical Preparation and Characterization of a Gold Nanoparticles Graphite Electrode: Application to Myricetin Antioxidant Analysis

“…1 Various deposition procedures of gold nanoparticles (AuNPs) on carbon electrodes have been studied including electro-polymerization, [5][6][7][8] electro-grafting methods 9,10 and electro-deposition. [11][12][13][14][15] The latter method provides a much easier, rapid and lower cost procedure 13 because the preparation is less tedious and involves minimum chemical usage.…”
