Synthesis of Highly-Ordered V₂O₅ Nanowires by AAO Template and its Electrocatalytic Activity for Dopamine Electro-Oxidation

Abstract:

Highly-ordered V₂O₅ nanowires were prepared by sol-gel strategy using anodic aluminum oxide (AAO) as a template. The morphologies, structures and components of the nanowires were characterized by XRD, SEM and XPS. The results indicated high-ordered and uniformly distributed V₂O₅ nanowires were obtained, and the length and diameter were dependent on the diameter and the thickness of the applied AAO template. The V₂O₅ nanowires modified glassy carbon electrode (GCE) was used to investigate the electrochemical properties of dopamine (DA), V₂O₅ nanowires exhibited an excellent electrocatalytic behavior on DA.
