preparation example Construction

[0030] A carbon-doped MoS 2 The preparation method of / CoP / C composite antibacterial material comprises the following steps:

[0031] (1) Add nano-carbon spheres, cobalt nitrate hexahydrate, urea and water into a beaker, stir for 0.5-2 h until uniform, and obtain a mixed solution. In the mixed solution, the concentration of nano-carbon spheres is 20 ~ 1000 mg / 50 mL, The concentration of cobalt nitrate hexahydrate is 0.01~1.00 mol / L, and the concentration of urea is 0.01~1.00 mol / L;

[0032] Then add the mixed solution into the reaction kettle, and then put the reaction kettle in an oven for hydrothermal reaction, the temperature of the hydrothermal reaction is 100 ~ 180 ℃, and the time of the hydrothermal reaction is 8 ~ 20 h;

[0033] (2) Centrifuge and wash the mixed solution obtained from the above hydrothermal reaction, and obtain an orange-red solid powder after vacuum drying. The vacuum drying is carried out in a vacuum oven at a temperature of 55-65°C for 10-14 h;

Abstract

The invention discloses a carbon-doped MoS2 / CoP / C composite antibacterial material, a preparation method and application thereof, and belongs to the technical field of material preparation and antibacterial materials. The method comprises the following steps: (1) uniformly stirring carbon nanospheres, cobalt nitrate hexahydrate, urea and water to obtain a mixed solution, putting the mixed solution into a reaction kettle, then putting the reaction kettle into a drying oven, and carrying out a hydrothermal reaction; (2) centrifuging, washing and drying the mixed solution obtained by the hydrothermal reaction to obtain solid powder; (3) putting the solid powder and sodium hypophosphite into a tubular furnace, and calcining in a nitrogen atmosphere to obtain carbon-doped CoP / C; (4) adding CoP / C, thioacetamide and sodium molybdate into a beaker, uniformly stirring to obtain a mixed solution, putting the mixed solution into a reaction kettle, then putting the reaction kettle into a drying oven, and carrying out a hydrothermal reaction; and (5) centrifuging and washing the mixed solution obtained by the hydrothermal reaction, and drying to obtain the carbon-doped MoS2 / CoP / C composite antibacterial material. The composite material is excellent in antibacterial performance, short in reaction time and low in experiment cost, and has great industrial application potential.

Description

technical field [0001] The invention belongs to the technical field of antibacterial materials, in particular to carbon-doped MoS 2 / CoP / C composite antibacterial material and its preparation method and application. Background technique [0002] Bacterial infection is one of the most serious unavoidable risks for human beings in the world, whether in medicine, food or other fields. According to reports, the global food production industry loses approximately billions of dollars annually due to the presence of foodborne bacteria. On the other hand, a large number of patients die from postoperative infection every year. At present, antibiotics have become effective drugs for inhibiting bacterial growth. However, the overuse, misuse and improper handling of antibiotics has led to the evolution of bacterial resistance, with resistant strains able to survive and even reproduce in the presence of antibiotics, which have been detected in groundwater. To make matters worse, anti...
