Preparation of PtRu/C electrocatalysts by hydrothermal carbonization using different carbon sources. In: INTERNATIONAL SYMPOSIUM SCIENTIFIC BASES FOR THE PREPARATION OF HETEROGENEOUS CATALYSTS, July 11 - 15, 2010, Louvain-la-Neuve, France. <b>Proceedings...</b> p. 559-562.

The obtained PtRu/C electrocatalysts were characterized by EDX, TGA, XRD and BET surface area and pore volume measurements. The electro-oxidation of methanol was studied by chronoamperometry. The PtRu/C electrocatalyst prepared using cellulose as carbon source showed the best performance for methanol electro-oxidation. The electrocatalytic activity of obtained materials seems to be related to the pore volume and mesoporous structure.559-562openAccesselectrocatalystsplatinumtincarbonboron hydridesnitric acidethanoloxidationfuel cellsTexto completo de eventohttps://orcid.org/0000-0002-7011-8261https://orcid.org/0000-0003-0105-6519https://orcid.org/0000-0002-9287-6071
