| 内容記述 | To achieve both oxidation reactions at a more negative potential and better reactions in electrocatalytic glucose oxidation, AuCu alloy nanoparticles were synthesized and their activities for glucose oxidation in alkaline solution were investigated by voltammetric and controlledpotential electrolysis studies. Decanethiol-encapsulated (DT-) Aunano, DT-Au97Cu3 (m: atomic %), and DT-Cunano nanoparticles were synthesized, and their core sizes were determined to be 2 (1), 2 (1), and 4 (2) nm, respectively. To remove the DT monolayer from the DT-Aunano, DTAu97Cu3 and DT-Cunano nanoparticles, nanoparticle-modified plastic-formed carbon plate (PFC) electrodes were heated at 300 ˚C for 2 h. Elimination of the DT was confirmed by FT-IR and XPS measurements. The surface metal atomic content ratios of DT-Au97Cu3 eventually changed to Au77Cu23, after the heat-treatment. The voltammetric behavior of electrocatalytic glucose oxidation at the Au77Cu23 nanoparticle-modified electrodes in alkaline solution was similar to the Aunano nanoparticle-modified electrodes, in which the potential was more negative than a Cunano nanoparticle-modified electrode and bulk-like Cu electrodes. Upon controlled-potential electrolysis, Au77Cu23 nanoparticle-modified electrodes gave gluconolactone and formate as main products, which indicated that electrocatalytic oxidation was promoted in comparison with the Aunano nanoparticle-modified electrodes. It is concluded that Au77Cu23 nanoparticles have both advanced properties of Aunano and Cunano nanoparticles for glucose oxidation. |
