Silver nanoparticles on UiO-66(Zr)metal-organic frameworks for water disinfection application
文献摘要：
Drinking water disinfection is an essential process to assure public health all over the world.In this study,silver nanoparticles(AgNPs)on UiO-66(Zr)Metal-Organic Frameworks(Ag@UiO-66)is proposed as a potential water disinfection strategy.AgNPs are synthesized using polyvinyl pyrrolidone(PVP)as stabilizing agent,and sodium borohydride as reducing agent are subsequently embedded on UiO-66,a high-stability organometallic framework.The effect of premixing time,reaction time and reactant concentration on the loading rate of AgNPs on UiO-66 was investigated.The maximum load rate of AgNPs on UiO-66 could reach 13％when the premixing time is 3 h,the reaction time is 45 min and the concentration of AgNO3 is 10 ug/mL.The formation of AgNPs loaded on UiO-66 was observed and confirmed with ultraviolet and visible spectrophotometry(UV-Vis),scanning electron microscopy(SEM),infrared emission spectroscopy(IES)and X-ray diffraction(XRD)analysis.Ag@UiO-66 exhibited strong antibacterial activity against both Gram-negative Escherichia coli and Gram-positive Staphylococcus aureus,with minimum inhibitory concentrations(MIC)of 64 and 128 pg/mL,respectively.The germicidal efficacy of Ag@UiO-66 enhanced significantly as the temperature rose from 4 ℃ to 37 ℃.The results indicate that Ag@UiO-66 is potential candidate as a feasible water disinfection material.
