What is Electrocatalytic Oxidation of Glucose at Gold–silver Alloy, Silver and Gold Nanoparticles in an Alkaline Solution about?
Gold, silver and gold-silver alloy nanoparticles capped with decanethiolate monolayer shells (DT-Au, DT-Ag and DT-Au/Ag) were synthesized, with core sizes 2.3 (±1.0), 3.3 (±1.0) and 2.0 (±1.0) nm, respectively. To activate the synthesized nanoparticles for the electrocatalytic oxidation of glucose, nanoparticles were treated at 300 °C for 2 h. Heat-treated nanoparticles surfaces were characterized by FT-IR, X-ray photoelectron spectroscopy (XPS), thermogravimetric analysis (TGA), scanning electron microscopy (SEM) and cyclic voltammetry (CV). The elimination of C-H alkyl chains and thiolates from DT capped Au and Au/Ag nanoparticles was evident post heat-treatment by TGA, FT-IR and XPS investigations. In DT-Ag nanoparticles, C-H chains from DT were eliminated by heat-treatment, though thiolate was still present on nanoparticle surfaces. However, the thiolate from DT was eventually removed by further oxidation and reduction cycle treatments in an alkaline solution. After heat-treatment at 300 °C for 2 h, the surface content ratio of Au and Ag changed from Au:Ag(84:16) to Au:Ag(73:27). This tendency to increase the surface content ratio of Ag after heat-treatment was also observed in
