Abstract

To elucidate the effect of voltage and concentration on the elctrodeposition of ZnCo nanowires, we have studied the deposition of ZnCo nanowires by XRD and SEM. The structure of ZnCo alloy nanowires changes by changing the concentration of electrolyte as 100-x g/l Co100-xZnx (0≤x≤15), at constant voltage -1.6, and fixed pH 3. XRD results show that change in concentration can transform the crystal structure of electrodeposited Co100-xZnx from crystalline to amorphous. Furthermore, similar behavior from crystalline to amorphous was also observed for ZnCo electrodeposited nanowires at various potentials (-1.6V, - 2.5V, and - 3.0V) from the bath containing Co95g/l and Zn5g/l, pH 3 and at room temperature. We argued that this change in structure of ZnCo nanowires can be attributed to the faster growth rate of Zn than Co. These results can be explained by the electron tunneling theory. The workfunction of Zn (4.33eV) is smaller than Co (5.0eV) and the wavefunction of Zn metal has a larger overlap with orbital wavefunction of Zn ions, which leads the faster growth rate of Zn and hence influenced the structure of ZnCo alloy nanowires.
