Synthesis of Pd Dendritic Nanowires by Electrochemical Deposition

摘要

Pd dendritic nanowire electrodes were synthesized by the electrodeposition method with different reduction potentials and deposition times. In particular, it was found that during the electrochemical deposition process, the Pd dendritic nanowire grew along the < 111 > direction resulting from the favorable adsorption of the sulfuric acid anion on the Pd (111) plane. With an increased potential, the branches of the dendritic nanowires with single crystal structure became longer in length and thinner in thickness. In addition, depending on reduction potentials, the diameters of main and side branches in the Pd dendritic nanowires were almost the same without respect to the deposition time.
