“…The electrochemical effect of the Ag nanoparticles on the GF is discussed. We chose silver nanoparticles (as model electro-active nanoparticles) due to the fact that they possess a very high surface area to volume ratio, and have been shown to exhibit electrochemical properties that make them suitable for potential application in electrochemical devices such as sensors [29][30][31] and in fuel cells (i.e. hydrogen-evolution reaction [32] and oxygen-reduction reaction [33]).…”

Silver metal nanoparticles were decorated by electron beam evaporation on graphene foam (GF) grown by chemical vapour deposition. X-ray diffraction, Raman spectroscopy, scanning and transmission electron microscopy, and atomic force microscopy were used to investigate the structure and morphology of the graphene foam/silver nanoparticles (GF/Ag). Both samples were tested as electrodes for supercapacitors. The GF/Ag exhibited a significantly higher capacitive performance, including a specific capacitance value of (~110 Fg -1 ) and excellent cyclability in a three-electrode electrochemical cell. These results demonstrate that graphene foam could be an excellent platform for metal particles for investigating improved electrochemical performance.

“…In the literature, the electrocatalytic oxidation of glucose in alkaline medium was studied on Cu, Ag-Au, Au-Pt, Ag, Pt and Au materials [21][22][23][24][25][26][27][28][29][30][31]. In alkaline and neutral media, gold appeared as an excellent electrocatalyst for several saturated oxygenated organic compounds due to its catalytic activity at low potentials compared to the other catalysts in the same conditions [22,25,30].…”

Shape-dependent electrocatalytic activity of free gold nanoparticles toward glucose oxidation

The synthesis of shape and size-controlled free gold nanoparticles (AuNPs) was achieved by wet chemical methods. The UV-vis spectroscopy measurements and transmission electron microscopy characterizations confirmed the fine distribution in size and shape of the AuNPs. The zeta potential measurements permitted the evaluation of the stability of the AuNPs suspension. For the first time, the shape dependence on the electrocatalytic activity of these NPs is thoroughly investigated. The underpotential deposition (UPD) of lead reveals that their crystallographic facets are affected by their shape and growth process. Moreover, the glucose oxidation reaction strongly depends on the shape of AuNPs. Indeed, the gold nanocuboids (GNCs) and the spherical gold nanoparticles (GNSs) are significantly more active than the gold nanorods (GNRs) followed by the polyhedrons (GNPs). The oxidation process occurs at low potential for GNCs whereas the current densities are slightly higher for GNSs electrodes. Most importantly, the control of the shape and structure of nanomaterials is of high technological interest because of the strong correlation between these parameters and their optical, electrical and electrocatalytic properties.

“…Although the direct oxidation has several advantages, such as easy electrode preparation, long device lifetime and high thermodynamic efficiency in fuel cell applications, it has not been well investigated, and only a few significant works address this subject [3,4].…”

The electrocatalytic properties of nanostructured gold electrodes for glucose electro-oxidation in KOH were investigated by cyclic voltammetry and compared with a commercially available polycrystalline gold electrode. These electrodes were prepared by depositing gold nanoparticles from a sol onto different carbonaceous conductive supports: glassy carbon, carbon cloth and graphite paper. The gold sol was prepared reducing an aqueous solution of tetrachloroauric acid with sodium borohydride. In order to improve gold nanoparticle adhesion, the substrate surfaces were treated with warm concentrated nitric acid. Gold on treated carbon cloth turned out to be a very promising anode for glucose electro-oxidation. In order to better understand the glucose oxidation its pH dependence as well as sorbitol (the glucose reduction product) electroxidation were investigated.
