Template-assisted synthesis and catalytic property of copper nanowires

Abstract

Porous anodic aluminum (PAA) templates with uniform diameter pores were prepared by two step anodic oxidation method. The resultant PAA was characterized using field emission scanning electron microscopy (FESEM), and the preparation parameters of PAA templates were investigated. The barrier of PAA was dissolved by electrolyzing neutral solutions with PAA as a cathode and carbon electrode as an anode. Copper nanowires were synthesized with PAA templates by direct current electrodeposition. The resultant copper nanowires were characterized using FESEM. Carbon nanofibers were synthesized by using acetylene as carbon source and copper nanowires as catalysts through chemical vapor deposition. The morphology of carbon nanofibers was characterized using FESEM. It is observed that the product was a film-like and the diameter of fibers was tens of nanometers.
