Özet

The results showed that the catalytic activity of Pt₈₀Sn₁₀Ni₁₀/C and Pt₈₀Sn₁₀Pd₁₀/C for electrooxidation of ethanol is directly favoured to acetic acid potential at around 0.25 and 0.3V vs. RHE, respectively. These suggest that the addition of Ni or Pd to PtSn greatly enhances the formation of acetic acid at lower potential. However, Pt/C, Pt₈₀Sn₁₀Ni₁₀/C and Pt₈₀Sn₁₀Rh₁₀/C electrocatalysts showed a better performance than Pt₉₀Sn₁₀/C, Pt₈₀Sn₁₀Co₁₀/C and Pt₈₀Sn₁₀Pd₁₀/C electrocatalysts for the production of CO₂ during ethanol oxidation. Therefore, the pathway forming CO₂ is favoured by the presence of Ni and Rh in the PtSn.
