Abstract

The invention discloses a method for preparing a lead hydroxide nano-rod, belonging to the technical field of nanometer material preparation. The method is characterized in that lead nitrate and soluble chloride are dissolved in de-ionized water according to a mol proportion of 1:1-1:10 to prepare a solution; the solution is heated to 50-90 DEG C; alkali is added into the solution according to the mol proportion of the lead nitrate and the alkali substance of 1:3; the solution is stirred to obtain white participate; the white participate is filtered, washed and dried to obtain the lead hydroxide nano-rod. The lead hydroxide nano-rod is a hexagon structure with the length of about 50 micrometers and the diameter of 20-500 nanometers. The method has simple and convenient operation, high yield and no pollution to the environment.

Description

technical field [0001] The invention relates to a method for preparing nanorods, in particular to a method for preparing lead hydroxide nanorods by using liquid-phase chemical reaction. Background technique [0002] Quasi-one-dimensional nanomaterials, such as nanofibers, nanorods, etc., are nanoscale in the two-dimensional direction, and their major diameters are large. Compared with bulk materials that are all three-dimensional on a macro scale, they have unique physical and chemical properties, such as small size effects, quantum effects, surface effects, etc., and will display unique optical, electrical, and catalytic properties. [0003] At present, there are many methods for preparing quasi-one-dimensional nanomaterials, such as chemical vapor deposition, physical evaporation, template method, electrochemical deposition method, solid phase method, hydrothermal method, etc. [0004] Lead hydroxide has a wide range of applications, such as staining cells, as absorbents,...
