Resumo
Ni/Carbon was prepared in two steps: initially cellulose as carbon source and NiCl2$6H2O as catalyst of the
carbonization process were submitted to hydrothermal treatment at 200 C and further to thermal treatment
at 900 C under argon atmosphere. The obtained material contains Ni nanoparticles with face-centered cubic
(fcc) structure dispersed on amorphous carbon with graphitic domains. PtRu/C electrocatalysts (carbonsupported PtRu nanoparticles) were prepared by an alcohol-reduction process using Ni/Carbon as support. The
materials were characterized by thermogravimetric analysis, energy-dispersive X-ray spectroscopy, Fourier
transform infrared spectroscopy, X-ray diffraction, transmission electron microscopy and tested as anodes in
single direct methanol fuel cell (DMFC). The performances of PtRu/C electrocatalysts using Ni/Carbon as
support were superior to those obtained for PtRu/C using commercial carbon black Vulcan XC72 as support.
