Abstract

The invention discloses a nano composite antibacterial material and a preparation method and application thereof. The antibacterial material comprises vanadium pentoxide and bismuth vanadate according to a molar ratio of 0.30-1.50; the preparation method comprises the following steps: 1), dropwise adding hydrochloric acid into NH4VO3 solution, dropwise adding into hydrazine hydrate solution, stirring at room temperature, and suction filtering to obtain a reaction product; 2), adding the reaction product into Bi(NO3)3.5H2O solution, ultrasonically mixing, dropwise adding ammonia water to regulate pH of a reaction system until alkalinity to obtain a reaction mixture, and stirring to react the reaction mixture to obtain filter cake; 3), drying and calcining the filter cake to obtain the nano composite antibacterial material; the application refers to application of the antibacterial material in the preparation of antibacterial drugs.

Description

technical field [0001] The invention relates to an antibacterial material and its preparation method and application, in particular to a nanocomposite antibacterial material and its preparation method and application. Background technique [0002] With the overall progress of human society, people are more and more concerned about environmental issues, and it has gradually become a social consensus to reduce and effectively prevent the interference and harm of microorganisms in human settlements to human life, and to reduce the resulting bacterial infection. Among the many measures to control environmental microorganisms, inorganic antibacterial has become a means of controlling microorganisms because of its special effects, safety and hygiene. Especially in recent years, nano-TiO 2 The representative photocatalyst has been found to be a good bactericide, which can not only effectively kill bacteria, but also degrade the compounds released by bacteria at the same time, and ...
