Resumo
PtSnO2/C with Pt:SnO2 molar ratios of 9:1, 3:1 and 1:1 prepared by an alcohol-reduction
process were evaluated as anodicelectrocatalysts for direct ethanol fuel cell (DEFC). Acetaldehyde, acetic acid and mixtures of them with ethanol were also tested as fuels. Single
cell tests showed that PtSnO2/C electrocatalysts have a superior electrical performance for
ethanol and acetaldehyde electro-oxidation when compared to commercial Pt3Sn/C(alloy)
and Pt/C electrocatalysts. For all electrocatalysts, no electrical response was observed
when acetic acid was used as a fuel. For ethanol electro-oxidation, the main product was
acetaldehyde when Pt3Sn/C(alloy) and Pt/C electrocatalysts were employed. Besides, PtSnO2/
C electrocatalysts led to the formation of acetic acid as the major product. CO2 was formed
in small quantities for all electrocatalysts studied. A sharp drop in electrical performance
was observed when using a mixture of ethanol and acetaldehyde as a fuel, however, the
use of a mixture of ethanol and acetic acid as a fuel did not affect the DEFC performance.
