Composition–activity relationships of carbon electrode-supported bimetallic gold–silver nanoparticles in electrocatalytic oxidation of glucose

Electrocatalytic oxidation of d-glucose at nanoporous Au and Au–Ag alloy electrodes in alkaline aqueous solutions

“…2(a) show two oxidation peaks in the positive-going potential scan and two reduction peaks in the negative-going potential scan. The voltammetric shape is very similar to that of bimetallic Au-Ag nanoparticles previously reported by Tominaga et al [18] except that the oxidation peak and the reduction one at low potentials are composed of two current peaks respectively. The whole CV curve seems to be composed of individual oxidation and reduction peaks of Au and Ag components, revealing that there exist Au and Ag metal domains in the Au-Ag alloy.…”

Copper/nickel nanoparticle decorated carbon nanotubes for nonenzymatic glucose biosensor

“…[5][6][7][8][9] and their metallic alloys (PtPb, PtIr, PtRu, AuPt, AuAg, etc.) [10][11][12][13][14][15] for the development of nonenzymatic glucose sensors. However, the high cost of electrode materials may limit their commercial applications since the ability to produce glucose sensors at low cost is a major market requirement.…”

Glucose Oxidation on Gold-modified Copper Electrode

“…[10][11][12][13][14][15][16][17][18][19][20][21][22] In more detail, several single metal catalysts using Au, 10,12,[14][15][16]19,22 Pt, 10,12,16,18 Cu 10,20 and Ni 10,11,21 have been reported to have significant activities toward glucose oxidation. Particularly, Pt is a well-known catalyst for proton exchange membrane fuel cells and direct methanol fuel cells as both anode and cathode catalysts.…”
