Copper Catalysts based on carbon–carbon fiburous materials for ethanol dehydrogenation

Resumo

The possibility of using new carbon–carbon composites as supports for a copper catalyst for ethanol dehydrogenation was demonstrated. The composites, which represented carbon nanostructures (single-walled carbon nanotubes or carbon nanofibers) attached to the surface of carbon microfibers, were prepared by essentially different procedures. Copper catalysts deposited on these supports exhibited different activity in the ethanol conversion, which is associated with the distribution and size of copper particles.
