Abstract： |
The present invention relates to the preparation process of nanometer metal material. The nanometer iron tube array synthesizing process includes compounding electrolyte liquid with ferrous sulfate, boric acid and ascorbic acid at room temperature; setting the electrolyte liquid in an electrolytic bath, setting the porous alumina film, which has one side with conducting gold or silver film as cathode connected to the negative pole of power supply, into the electrolyte liquid, inserting the metal iron rod connected to the positive pole of power supply as the anode into the electrolyte liquid, and electrolysis in constant current strength of 10-20 mA. The said process can synthesize nanometer iron tube array of nanometer iron tube in outer diameter of 80-100 nm, inner diameter of 30-50 nm and total length up to 60 microns. The present invention is expected to find its application in microelectronic device, magnetic record and other fields. |
