Abstract

The invention discloses a preparation method of CaB6 nanoparticles. CaCl2 is successfully reduced by borane at room temperature through a liquid-phase plasma technology to synthesize CaB6 nanoparticles. Compared with commercial CaB6, the CaB6 nanoparticles prepared by the method disclosed by the invention are larger in specific surface area and stronger in antibacterial effect. Compared with amikacin and vertilmicin sulfate, the CaB6 nanoparticles prepared by the method disclosed by the invention show stronger antibacterial activity on morganella morganii. The CaB6 nanoparticles are expected to expand the wide application in the clinical treatment fields of urinary tract infection, wound infection, pneumonia, septicemia, diarrhea and the like due to excellent antibacterial property of morganella morganii.

Description

Technical field [0001] The present invention relates to a CaB 6 The nanoparticle method belongs to the technical field of advanced nanomaterial preparation. Background technique [0002] CaB 6 It is an important material with excellent comprehensive performance and is widely used in national defense and civilian industries. In addition, there are relatively mature methods for preparing CaB 6 Nano-micron powder. However, at this stage, CaB 6 The preparation of nano-micron powder is mainly prepared by high-temperature sintering, which not only consumes energy but also time. Therefore, open up new green synthetic methods or technical approaches to prepare CaB 6 It seems very necessary. [0003] Recently, the solution plasma process (SPP) has become an effective way to prepare metal borides. The reported metal borides synthesized by SPP technology include: nickel-boron, cobalt-boron, europium-boron and ytterbium-boron compounds. Summary of the invention [0004] The invention uses l...
