Abstract

The invention discloses a method for preparing boron oxynitride nanoflowers. According to the method, the boron oxynitride nanoflowers are successfully prepared at room temperature for the first timethrough inducing concentrated nitric acid to oxidate CuB23 nanoflowers through a liquid-phase plasma technology in nitroimidazole ionic liquid. Compared with commercial boron oxynitride, the boron oxynitride nanoflowers prepared by the method have the advantages that the specific surface area is larger, and the bacteriostasis effect is higher. Compared with amikacin and kanamycin, the boron oxynitride nanoflowers prepared by the method show higher antibacterial activity to Staphylococcus aureus. Due to excellent Staphylococcus aureus inhibiting performance, applications of boron oxynitride compounds in the aspects of air purification, sewage disinfection and the clinical medical treatment fields of skin, nasal cavities, throats, intestines and stomachs, carbuncles, suppurated furuncles andthe like are advantageously extended.

Description

technical field [0001] The invention relates to the technical field of nanomaterials, in particular to a preparation method of boron nitride nanoflowers containing oxygen. Background technique [0002] Oxy-boron nitride is an important electro-adsorption material. With the development of nanotechnology, it is found that the shape structure has a great influence on its performance. However, because the preparation of oxy-boron nitride is not easy, there are not many studies on its morphology and structure effects. For example, only the structure-activity relationship of oxy-boronitride nanosheets for adsorption of heavy metal ions has been reported so far, which severely limits its practical application. [0003] In summary, it is very meaningful to study the synthesis technology of boron nitride with novel morphology. At present, there is no research report on oxy-boron nitride nanoflowers. In addition, CuB 23 Oxy-boron nitride compounds cannot be produced by reacting w...
