Embodiment 1

[0027] A method for synthesizing basic zinc chloride single crystal nanorods of the present invention, comprising the steps of: preparing a concentration of 0.16mol L -1 200mL of zinc chloride solution, under the condition of magnetic stirring, ammonia water was added dropwise with a material ratio of 1:5. After reacting for 30min, the resulting suspension was centrifuged, and the sample was washed with deionized water and then centrifuged. Repeat three times, and add the sample amount 10 times the volume of deionized water, heated in an oven at 80°C for 2 hours, then allowed to stand for 16 hours. Wash the sample with absolute ethanol and centrifuge, repeat three times, and dry in an oven at 40°C for 6 hours to obtain a white basic zinc chloride single crystal nanorod powder with a uniform shape, a diameter of about 70 nm, and a length of about 400 nm, as shown in figure 1 SEM photographs and figure 2 The transmission electron microscope photo is shown.

Abstract

The invention discloses a synthesis method of basic zinc chloride monocrystal nanorods. The synthesis method is characterized by comprising the following steps: taking zinc chloride and ammonia water as raw materials and reacting the raw materials at the room temperature; washing with deionized water, and centrifuging; adding deionized water which is 10-20 times of the volume of a sample, heating in an oven at 80 DEG C for 2 hours and then standing still; washing the sample with absolute ethyl alcohol, and then centrifuging; and drying in the oven at 40 DEG C for 6 hours to prepare the basic zinc chloride Zn5(OH)8Cl2.H2O monocrystal nanorods with diameters of about 70 nm and lengths of 400nm. The product prepared by the synthesis method has a wide application prospect and can be applied to various fields such as chemical synthesis, photocatalysis, sensors and nano devices, and the synthesis method is in no need of any additives or expensive equipment, and has the advantages of simplicity and convenience in operation, easiness in control and industrialization, low production cost, and the like.

Description

technical field [0001] The invention relates to a one-dimensional single-crystal basic zinc chloride nanometer material, in particular to a synthesis method of a basic zinc chloride single-crystal nanorod. Background technique [0002] The basic zinc chloride Zn that the present invention relates to 5 (OH) 8 Cl 2 ·H 2 O is a zinc salt compound, which is currently widely used as a trace zinc element additive in animal feed additives. For example, Huang Yiqiang uses zinc waste to react with saturated zinc chloride solution, basic zinc carbonate to react with hydrochloric acid, zinc oxide to react with zinc chloride, zinc oxide to react with hydrochloric acid, zinc hydroxide to react with zinc chloride, sodium hydroxide or ammonia water Basic zinc chloride was prepared by reacting with zinc chloride and other methods, and the basic zinc chloride was used as a feed additive to investigate its effect on the growth and feeding of piglets, broilers and other animals. When zinc...
