Au hollow spheres have been prepared by dissolving Ag and polystyrene in Au/Ag supported on polystyrene spheres. The Au hollow spheres (HS) are good electrocatalysts for glycerol oxidation and show excellent higher activity and better steady-state electrolysis than Au/C in alkaline medium. The value of onset potential is more 143 mV shifted negatively on the Au HS electrode than that on the Au/C electrode. The current for glycerol oxidation on the Au HS electrode begins to rise much more sharply at more negative potential than that on the Au/C electrode.
