Abstract

The invention discloses a preparation method for a nickeled iron nanorod and belongs to the technical field of preparation of nano materials. The method specifically comprises the steps that ferric chloride and nickel chloride are evenly mixed at first, then mixed powder of the ferric chloride and the nickel chloride is arranged in a high temperature zone of a reaction vessel, an alumina wafer isarranged in a low temperature zone of the reaction vessel, the reaction vessel is sealed and vacuumized, the high temperature zone is heated to 1000-1100 DEG C, the low temperature zone is heated to 100-200 DEG C, heat preservation is conducted for 0.5-2 h, and an alumina wafer of which the surface contains brown depositions is obtained; and then the alumina wafer is fixed in the middle of the reaction vessel, ferric chloride, nickel chloride, sodium borohydride and ethyl alcohol are mixed and then are arranged in the reaction vessel and sealed, and heat preservation is conducted for 24-72 h at 200-300 DEG C. The two-step reaction process is adopted, the preparation process is simple and easy to control, and the obtained nickeled iron nanorod has good application prospects in the aspects such as electron devices, magnetic devices and microwave devices.
