Abstract
Au-Pt/SnO 2 /GC composite electrode was prepared by self-assembling Au-Pt nanoparticles on SnO 2 film, which was deposited on actived glassy carbon (GC). Atomic force microscopy (AFM) and scanning electron microscopy (SEM) images revealed that dense and uniform Au-Pt particles with 25-nm diameter were dispersed on SnO 2 film. X-ray photoelectron spectroscopy (XPS) results proved that there was an interaction between Au-Pt nanoparticles and SnO 2 support. Electrochemical experiments showed that Au-Pt/SnO 2 /GC composite electrode had a good electrocatalytic activity to the oxidation of methanol.
