Abstract

PtSn/C and Pt₅Sn₄M/C (M = W, Pd, Ni) electrocatalysts were prepared by impregnation method using NaBH₄ as a reducing agent. Chemical composition, crystalline size, and alloy formation were determined by EDX, XRD and TEM. The average particle sizes of the synthesized catalysts were approximately 3.64-4.95 nm. The electro-chemical properties were measured by CO stripping, cyclic voltammetry, linear sweep voltammetry, and chronoamperometry. The maximum specific activity of the electro-catalysts for ethanol electro-oxidation was 406.08 mA m^-2 in Pt₅Sn₄Pd/C. The poisoning rate of the Pt₅Sn₄Pd/C (0.0017% s^-1) was 4.5 times lower than that of the PtSn/C (0.0076% s^-1).
