Aluminum-doped zinc oxide one-dimensional nanorod and preparation method thereof

The invention discloses a preparation method for an aluminum-doped zinc oxide one-dimensional nanorod. The preparation method comprises the steps of dissolving zinc salt into first organic solvent, preparing and obtaining an organic solution of the zinc salt, according to the fact that the molar ratio of aluminum to zinc is in a range of 0.1:100 to 5:100, adding soluble aluminum salt into the organic solution of the zinc salt, obtaining a mixed solution, dissolving strong base into second organic solvent, preparing and obtaining an organic solution of the strong base, under the condition of stirring, adding the organic solution of the strong base into the mixed solution in a dropwise mode, continuously stirring the mixed solution until the mixed solution changes into a settled solution, stopping adding in the dropwise mode, placing the settled solution in a high pressure reactor at the temperature of 120 DEG C to 180 DEG C, keeping the temperature for 20 hours to 36 hours, cooling, centrifuging, cleaning and drying the solution, and obtaining the aluminum-doped zinc oxide one-dimensional nanorod. The preparation method for the aluminum-doped zinc oxide one-dimensional nanorod is low in energy consumption, simple and low in cost. In addition, further disclosed is the aluminum-doped zinc oxide one-dimensional nanorod.
