Influence of the carbon support on the PtSn anodic catalyst for the electrochemical reforming of ethanol

Several anodic catalysts based on Pt–Sn (3:1 mass ratio) and 20% total metal loading were prepared on different carbonaceous supports (functionalized and non-functionalized low-density nanofibers, graphite oxide, expanded graphite, graphene flakes and β-SiC), to identify an alternative for the tradi...

Of the materials tested, Pt–Sn supported on non-functionalized low-density nanofibers (CNF LS) showed the highest electro-catalytic activity vs. the traditional support. This result was attributed to the combination of different properties such as high surface area and dispersion of the Pt–Sn nanoparticles, high electrochemical active surface area and high basicity. This anodic catalyst was chosen for the development of a Membrane Electrode Assembly (MEA) and tested for the electrochemical reforming of ethanol. A high activity was obtained (120 mA cm−2 at 1.4 V and 80 °C) for hydrogen production.

De los materiales ensayados, el Pt-Sn soportado sobre nanofibras de baja densidad no funcionalizadas (CNF LS) mostró la mayor actividad electrocatalítica frente al soporte tradicional. Este resultado se atribuyó a la combinación de diferentes propiedades, como la elevada superficie y dispersión de las nanopartículas de Pt-Sn, la elevada superficie electroquímicamente activa y la alta basicidad. Este catalizador anódico se eligió para el desarrollo de un conjunto de electrodos de membrana (MEA) y se probó para el reformado electroquímico del etanol. Se obtuvo una elevada actividad (120 mA cm-2 a 1,4 V y 80 °C) para la producción de hidrógeno. Además, se estudió la estabilidad del sistema y su posterior regeneración con vistas a su aplicación práctica.Elsevier202220222019info:eu-repo/semantics/articleapplication/pdfapplication/pdfhttp://hdl.handle.net/10578/29808reponame:RUIdeRA.
