Wherein, in step 1, in described dispersion soln, the concentration of zinc ion is 0.01～0.5mol/L, and equivalence nitrogen concentration of element is 2～8 times of zinc ion concentration.
Wherein, in described Zinc oxide/titanium dioxide composite nano materials, the mass percentage content of titanium dioxide is 3～20%.
The principle of preparation method of the present invention: the growth course of one-dimensional nano structure generally comprises nucleation and two stages of growth, first being formed seed crystal (nucleation) by reaction product supersaturation, these seed crystals speed of growth in one direction forms one-dimensional nano structure (anisotropic growth) far above other directions subsequently.Nucleation needs higher degree of supersaturation and fiercer reaction environment, but all directions speed of growth difference is less, generally yields substantial amounts of nano-particle；And the relatively mild reaction environment of growth needs of one-dimensional nano structure, gentle reaction environment is conducive to obtaining one-dimensional nano structure, but due to nucleation difficulty, one-dimensional nano structure negligible amounts, productivity is relatively low.Reaction environment required by the above-mentioned the two stage conflicts mutually and has bigger difference.In the present invention, adopting the raw material that can slowly release amino during heating in water and soluble zinc salt to react generation zinc oxide, reaction condition is comparatively gentle, is conducive to generating one-dimension zinc oxide nanostructured；The titania nanoparticles and the zinc oxide affinity that are simultaneously introduced are higher, can as the nuclearing centre of zinc oxide growth, solve the On The Nucleation required for one-dimension zinc oxide nanostructured, the quantity generating nanometer rods can be significantly improved, obtain the multi-branched one-dimensional nano structure being nucleating point or starting point with titanium dioxide in a large number, thus within reducing the size to 100 nanometers of nanometer rods, thus be conducive to increasing the specific surface area of product.
Beneficial effect: the preparation method of the present invention is capable of the high-volume synthesis of the Zinc oxide/titanium dioxide composite nano materials of one-dimensional nano structure, what it adopted is be directly synthesized in aqueous under normal pressure, not only reaction condition is gentle, energy consumption is low, cost is low and the product purity that obtains high, also has that surface area is big, good dispersion and a high advantage of degree of crystallinity simultaneously.
