摘要	Dendritic copper nanostructures of different morphologies were synthesized by a surfactant-free electrochemical method. Single crystal nature of the nanostructures was revealed from their X-ray diffraction and electron diffraction patterns. Mechanism of dendrite formation was discussed from thermodynamic aspects using the concept of supersaturation. Supersaturation of the copper metal reduced on the surface of the electrode was the crucial factor for the generation of different morphologies. Effects of applied potential, temperature, and the solution concentration on the supersaturation were studied. The NO(3)(-) and H(2)O(2) electroreduction ability of the dendritic materials was tested. Use of copper dendrite-modified electrode as NO(3)(-) sensor was demonstrated.; Dendritic copper nanostructures of different morphologies were synthesized by a surfactant-free electrochemical method.
