The invention provides a method for preparing one-dimensional zinc hydroxide nanorods through fast precipitation. The method appears to be particularly important for future industrial massive application and production. The method has the advantages of being efficient, fast and simple in the aspect of preparing a material, the great challenge, caused by quick crystallization of a precipitation reaction, of regulating a one-dimensional nanometer material is overcome, the one-dimensional nanometer zinc hydroxide (Zn(OH)2) is prepared, and the target material is precipitated quickly by using sodium sulfate (Na2SO4) as a precipitation agent. The N2SO4 is low in dissociation factor, OH- ions can be slowly released to balance the growth speed and the diffusion speed of the material, and the material can directionally grow in the one-dimensional direction in the growth process. The invention provides a morphology and phase regulating method for the Zn(OH)2 nanorods which are excellent in performance. The method has
