Iron oxide / nickel ferrite composite nanorod and synthesis method thereof

Abstract

The invention discloses an iron oxide / nickel ferrite composite nanorod and a synthesis method thereof, and belongs to the technical field of nano materials. The obtained composite nanorod is of a polycrystalline structure and is composed of a rhombohedral Fe2O3 crystal phase and a cubic NiFe2O4 crystal phase. The diameter of the composite nanorod is 10-100 nm, and the length of the composite nanorod is greater than 500 nm. The synthesis method comprises the following steps: dissolving ferric acetate and nickel acetate in deionized water, heating to 80-100 DEG C, preserving heat for 1-5 hours, cooling and drying to obtain a ferric oxide / nickel ferrite precursor; fully mixing the ferric oxide / nickel ferrite precursor with calcium chloride and sodium chloride, then putting the mixture into a corundum crucible, putting the crucible into a reaction furnace, and keeping the temperature at 800-1000 DEG C for 5-10 hours; the synthesis process is simple, complex equipment is not needed, control is easy, and the iron oxide / nickel ferrite composite nanorod has a large number of catalytic active sites, is expected to have good interface performance, catalytic activity and electrical and magnetic performance and has good application prospects in the aspects of catalysts, electrical devices and magnetic devices.
