Ni/Carbon hybride prepared by hydrothermal carbonization and thermal treatment as support for PtRu nanoparticles for direct methanol fuel cell. <b>Journal of Materials Science and Technology</b>, v. 29, n. 8, p. 747-751, 2013.

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.747-751openAccesscellulosehydrothermal systemscarbonizationalcoholsreductionelectrocatalystsplatinumrutheniumdirect methanol fuel cellsArtigo de periódico82910.1016/j.jmst.2013.05.004https://orcid.org/0000-0002-7011-8261https://orcid.org/0000-0002-9287-6071
