| Pd-Ag Alloy Nanowires: Facile Visible-Light-Assisted Synthesis and Electrocatalytic Activity toward Ethanol Oxidation |
|
| Abstract: Using palladium nitrate and silver nitrate as the metal precursor, ethanol and sodium citrate tribasic dehydrate as reducing agents and poly(vinyl pyrrolidone) (PVP) as a stabilizer and guiding agent, Pd-Ag alloy nanowires were synthesized via visible-light-assisted solution approach with a commercial incandescent lamp as light source. The morphologies, crystal structure and optical properties were characterized by field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), high resolution transmission electron microscopy (HRTEM), power X-ray diffraction (PXRD), and UV-visible spectroscopy, respectively. The electrocatalytic properties of the Pd-Ag alloy nanowires modified glassy carbon electrode for ethanol oxidation were investigated by cyclic voltammetry and chronoamperometry. The Pd-Ag alloy nanowires exhibited much better electrocatalytic performance than Pd nanoparticles toward ethanol oxidation reaction in alkaline media in terms of the electrocatalytic activity, anti-poisoning ability and stability. |
