In the present work, bi-metallic Pt-Sn electro catalysts were prepared by microwave assisted polyol method at 9:1, 7:3, and 5:5 Pt: Sn atomic ratios on carbon nanotube. The ethanol electro-oxidation activities of these catalysts were measured by cyclic voltammetry (CV). The effect of Sn addition to Pt for the improvement of ethanol electro-oxidation was also measured by CV measurements. Pt-Sn (07:03) catalyst exhibits the highest ethanol electro-oxidation activity. Furthermore, the rotating disk measurements were performed at 0-2000 rpm rotating rates on Pt-Sn (07:03) catalyst. The effect of ethanol concentration on ethanol electro-oxidation activity at varying ethanol concentrations (0.03 M-8.00 M) were measured on Pt-Sn (07:03) catalyst. CO stripping measurements were performed to determine the CO resistance of Pt-Sn electrocatalysts. As a result, CO oxidation onset potential decreases by the addition of Sn to Pt, revealing that Sn addition promotes the CO resistance of platinum.
