Enhancement of Ethanol Electro-Oxidation Activities on Pt/Natural Zeolite Catalysts

The electrochemical oxidation of ethanol on novel Pt-natural zeolite electrocatalyst has been studied. It was found that Pt/Zeolite (Pt mean size, 4.14 nm) had higher electrocatalytic activity and CO-tolerance suggested by the increase of oxidation current density and the onset potential of Pt/Zeolite, 0.06 V, which is much lower than that of Pt/MWCNTs.
