Adhesion of gold nanoparticles on an electrochemically pretreated glassy carbon electrode.
This study describes a simple new method for the adsorption of gold nanoparticles on a glassy carbon (GC) electrode. By electrochemically oxidizing the GC electrode and immersing it into a gold colloidal solution, one could induce the adhesion of the gold nanoparticles. The image of the field emission scanning electron microscopy confirmed that the nanoparticles were evenly distributed over the surface. A 2-aminoethanethiol self-assembled monolayer was formed on the surfaces of the adsorbed gold nanoparticles and a reductive desorption wave was observed during the reduction of the adsorbed 2-aminoethanethiol.
