摘 要:<正>Ni/Carbon was prepared in two steps:initially cellulose as carbon source and NiCI2·6H20 as catalyst of the carbonization process were submitted to hydrothermal treatment at 200℃and further to thermal treatment at 900℃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(carbon-supported 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 FtRu/C using commercial carbon black Vulcan XC72 as support.
