Embodiment 1

[0028] Three-dimensional van der Waals complex NiCl 2 (pyrazine) 2 synthesis

[0029] 1.0mmol of NiCl 2 ·6H 2 O and 2.0mmol of pyrazine were dissolved in 10ml of water and 5ml of acetone, and the acetone solution of pyrazine was slowly added dropwise to NiCl 2 In the aqueous solution, a sky blue solid precipitate gradually precipitated in the solution. After stirring for 0.5-1h, filter, wash the precipitate with 10ml of acetone, and vacuum dry to obtain the three-dimensional van der Waals complex NiCl 2 (pyrazine) 2 . Crystal structure see figure 1 .

[0043] The morphology of the AgCl nanoparticles prepared in Example 3 was characterized by a scanning electron microscope.

[0044] Antibacterial experiment of AgCl nanoparticles

[0045] The minimum inhibitory concentration (MIC) of AgCl nanoparticles against Escherichia coli was determined by broth dilution method. The measurement results show that the MIC of common AgCl nanoparticles is 0.625 mg / L, while the MIC of the square AgCl nanoparticles of the present invention is 0.078 mg / L. These results show that the square AgCl nanoparticles obtained by the method of the present invention have better advantages in terms of sterilization.

The structural formula of the three-dimensional van der Waals complex is NiCl 2 (pyrazine) 2 ; The size of the square AgCl nanoparticles is about 300-400nm, the shape is square, and the shape is uniform, and it is not easy to agglomerate. The size of the square AgCl nanoparticles described in the present invention is about 300-400nm, and the shape is uniform, and it is not easy to agglomerate, showing great application prospects in antibacterial aspects.

Description

technical field [0001] The invention relates to AgCl nanoparticles and a preparation method and application thereof, in particular to square AgCl nanoparticles and a preparation method and application thereof. Background technique [0002] Silver-based antibacterial agents have a long history of application and have played a significant role in human health. Silver ions have a strong bactericidal effect, even at a very low concentration, they still have obvious bacteriostatic effect, so in many fields, especially in medicine, Ag + It is widely used as an inorganic antibacterial material. Since the energy bandwidth of AgCl is 3.3eV, under the excitation of near-ultraviolet light, electrons can transition from the valence band to the conduction band, forming hole and electron pairs, activating oxygen in water and air, and generating hydroxyl radicals OH and active oxygen ions o 2- , Both of them have strong oxidizing ability, which can destroy the proliferation ability of b...
