Abstract：
 It is a kind of electro-chemistry synthesis method of metal Ni nano pipe ordered structure, and it refers to a kind of preparing craft of nano metal material. In the room temperature, the water solutions of NiSO4, NiCl2, H3BO4 are mixed together to make electrolyte. One surface of perforated Al2O3 film is sprayed with Au or Ag to make Au conducting film or Ag conducting film, so the film can be used as the negative pole of the electrochemical reaction, and it is linked with the negative pole of the electric source. The other surface is touched with the electrolyte. Then one end of the Ni filament is infixed into the electrolyte as the positive pole of the electrochemical deposition reaction, and the other one is linked with the positive pole of the electric source. At last, turn on the electric source, then we can get metal Ni nano pipe ordered structure. To sum up, the technology is easy, and the crude material is also easy to get. We can get the Ni nano pipe whose maximum length can reach 60 microns. Its external diameter is 80-100 nanometers, and the inner diameter is 30-50 nano. This method is expected to be used as electric conductor in the field of nanometer electronic device and so on.
