Abstract

Bimetallic Al–Cu and Al–Ag nanoparticles were synthesized by electric explosion of wires in an argon atmosphere. The mass ratio of aluminum and the second metal (Me = Cu or Ag) was ~ 90 : 10 and was controlled by the diameter of the dispersed metal wires. Mesoporous AlOOH–Me nanocomposite was obtained by simple oxidation of Al–Me precursors with water at a temperature of 60°С. The kinetic regularities of the oxidation of Al–Me nanoparticles in dilute aqueous suspensions were studied. The effect of the second metal on the structure, morphology, and antibacterial activity of nanocomposites against methicillin-resistant Staphylococcus aureus (MRSA) bacteria was studied. It has been shown that the synthesized AlOOH–Me nanocomposites possess high antibacterial activity and are promising and highly efficient antimicrobial agents.

介孔AlOOH-金属纳米复合材料的结构、形态和抗菌性能

摘要

双金属 Al-Cu 和 Al-Ag 纳米粒子是通过在氩气气氛中电爆炸导线合成的。铝和第二金属（Me = Cu 或 Ag）的质量比为～90:10，并由分散的金属线的直径控制。介孔 AlOOH-Me 纳米复合材料是通过在 60°С 的温度下用水简单氧化 Al-Me 前体获得的。研究了 Al-Me 纳米粒子在稀水悬浮液中氧化的动力学规律。第二金属对耐甲氧西林金黄色葡萄球菌纳米复合材料结构、形态和抗菌活性的影响(MRSA) 细菌进行了研究。结果表明，合成的 AlOOH-Me 纳米复合材料具有很高的抗菌活性，是一种很有前途的高效抗菌剂。
