Abstract
Bimetallic nanostructures are an interesting class of materials for numerous application fields due to their special characterization. In this study, NiCu carbon nanofibers nanocomposite (NiCuCNFs) were investigated as electrocatalyst for ethanol (EtOH) oxidation. nanocomposite were synthesized from calcination of electrospun sol-gel consisted of nickel acetate tetrahydrate (NiAc), copper acetate monohydrate (CuAc), and poly vinyl alcohol (PVA) in the presence of Ar/H-2 gas at 700 degrees C for 1h. The NFs appeared to have good electrical conductivity and electrocatalytic activity for ethanol oxidation, at the current density similar to 100 mA/Cm-2 and onset potential similar to 350 vs. Ag/AgCl. These enhanced properties are due to the influence synergistic of the bimetallic alloy and thin graphite layer.
