Abstract :
Mesocarbon microbeads (MCMB) supported
PtSn catalysts were prepared by alcohol
reduction method and characterized by XRD, FESEM
and EDX. XRD results show that the addition of Sn to
Pt/MCMB extends the fcc lattice parameters of platinum
and the particle size of PtSn/MCMB is about
2.6 nm, smaller than that of Pt/MCMB. The electrode
catalytic activity in the electro-oxidation of ethanol was
studied by cyclic voltammetry, Tafel plot, electrochemistry
impedance spectra (EIS) and chronoamperometry.
All the results showed that PtSn/MCMB gave
higher catalytic activity for ethanol electro-oxidation
than Pt/C (20 wt.% E-TEK).
