Synthesis method of basic zinc chloride monocrystal nanorods

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...

For example, Tengfa Long et al. prepared large-size plate-shaped Zn with an average particle size of about 50 μm. 5 (OH) 8 Cl 2 ·H 2 O and nanorod ZnO; Nan WU et al. prepared irregular micron-sized Zn by femtosecond laser irradiation 5 (OH) 8 Cl 2 ·H 2 O and Zn(OH) 2 Composite powder and nanorod ZnO with a diameter of 40-80nm; Marivone G et al. 2 As a raw material, when reacting with sodium hydroxide solution at 90°C to prepare ZnO, Zn 5 (OH) 8 Cl 2 ·H 2 Composite powder of O and ZnO, the particles are in the shape of nanorods, but the distribution is irregular and the size is not uniform

[0004] Comprehensive research status at home and abroad, in the existing technology of preparing basic zinc chloride, the production cost of some methods is too high, the by-products that some methods prepare are likely to cause environmental pollution, and the size prepared by some methods is too large, some The method cannot obtain basic zinc chloride with a pure phase structure, but exists in the form of a mixture. At the same time, there is still little research on basic zinc chloride nanomaterials, especially single crystal materials.
