Preparation method of nano ferrate/carbon nano tube composite materials

The invention discloses a preparation method of nano ferrate/carbon nano tube composite materials, which utilizes a carbon nano tube as a supporting material and adopts a method of solvothermal synthesis to prepare a series of nano ferrate/carbon nano tube composite materials which are even in dispersion, have magnetic property, include nano cobalt ferrite/carbon nano tubes, ferrous acid nickel/carbon nano tubes, ferrous acid copper/carbon nano tubes, zinc ferrite/carbon nano tubes, ferrous acid manganese/carbon nano tubes and the like, and have certain universality. Compared with the prior art, the preparation method of the nano ferrate/carbon nano tube composite materials utilizes ethanol as solvent. The prepared nano materials are uniform in grain size and excellent in performance and have good application prospect and economic benefits on aspects of photocatalysis sewage treatment, lithium ion batteries and the like.
