Abstract

Abstract : NiCu-carbon nanofibers (CNFs) composite was introduced as electrocatalyst for methanol oxidation. Nanofibers (NFs) were synthesized by calcination of electrospun nanofiber mats composed of nickel (II) acetate tetrahydrate, Copper (II) acetate monohydrate, and polyvinyl alcohol (PVA) in the argon/hydrogen atmosphere at 700°C for 2 hr. The introduced NFs showed a very good ectrocatalytic activity for methanol oxidation as compared tothat of Ni nanoparticles (NPs) and NiCNFs. As the current densities ∼110 mA/Cm 2, 85 mA/Cm 2, and 60 mA/Cm 2 for NiCuCNFs nanocomposite, NiCNFs, and Ni NPs, respectively, were obtained.
