与纯MOFs相比，贵金属@MOFs的核壳异质结构由于其独特的结构和广泛的应用而引起了极大的兴趣。在本研究中，我们成功合成了结构明确的核壳Ag@ZIF-8纳米线。通过检查不同时间间隔获得的产物来研究产物的生长过程，并且通过调节银纳米线的数量可以在技术上获得30至100 nm范围内的ZIF-8壳的厚度。 Ag@ZIF-8已被证明具有大的比表面和高的热稳定性。此外，还进一步测试了Ag@ZIF-8对枯草芽孢杆菌和大肠杆菌BL21的抗菌活性。结果表明Ag@ZIF-8核壳异质结构纳米线对两类菌株均具有有效的活性。 (C) 2017 Elsevier B.V. 保留所有权利。
Compared with pure MOFs, core-shell heterostructures of noble-metal@MOFs have attracted tremendous interest due to their unique structure and extensive applications. In the present study, we have successfully synthesized well-defined core-shell Ag@ZIF-8 nanowires. The products growth process has been investigated by examining the products obtained at different intervals and the thickness of ZIF-8 shell ranging from 30 to 100 nm can be technically obtained by tuning the quantity of Ag nanowires. Ag@ZIF-8 has been proven to possess large specific surfaces and high thermal stability. Additionally, the antibacterial activity of Ag@ZIF-8 is further tested against Bacillus subtilis and Escherichia coli BL21. The results reveal that Ag@ZIF-8 core-shell heterostructure nanowires have effective activities against the two types of bacterial strains. (C) 2017 Elsevier B.V. All rights reserved.
