| Abstract: | A new method is presented for nickel nanowire deposition in porous anodic alumina(PAA)(template) by direct current.The barrier layer of PAA was removed by electrolysis in neutral potassium chloride(solution) with the PAA as the cathode.The electrochemical behavior of Nickel ion and hydrogen ion on PAA was studied by measuring the polarization curves.The morphology and the crystal structure of the PAA and the nickel nanowires were characterized by SEM and XRD.The cyclic voltammogram of the PAA with the barrier layer eroded showed an(oxidation) peak in the first scan in a 0.5 mol/L phosphate buffer solution.The deposition potential of nickel ions on PAA was-1.0 V versus Ag/AgCl.The diameter of the nanowires was about 70~80 nm based on SEM.XRD showed that the deposited material was cubic nickel orienting along the(111) direction.After the barrier layer was eroded,PAA could be used directly as a template to fabricate nickel nanowire by direct current method. |
