Convenient arc-electrodeposition technique to synthesize CdS nanotubes at room temperature

An arc-electrodeposition technique to synthesize CdS nanotubes at room temperature was presented. THe mixture of Na₂S and KCl aqueous solution was used as electrolyte solution. In the arc-electrodeposition process, the colorless transparent electrolyte aqueous soltuion turned into yellow gradually, indicating the formation of CdS nanoparticles. It was found that the morphologies of the CdS nanoparticles were strongly affected by the composition of aqueous electrolyte solution.
