Synthesis of hierarchical ZIF-8/carbon nanotube structure via zinc hydroxide nanostrands as a butanol QCM nanosensor
A composite of ZIF-8 metal organic framework/multi-walled carbon nanotube (MWCNT) was synthesized at room temperature using zinc hydroxide nanostrands (ZHNSs) as the metal source. ZHNS not only served as a metal source but also acted as a template, confining the nucleation and growth of ZIF-8 on the MWCNT. This led to the low linker/metal ion molar ratio necessary for ZIF-8 synthesis. The resulting composite was used in the fabrication of a quartz crystal microbalance (QCM) nanosensor for detecting volatile organic compounds (VOCs). The nanosensor was assessed in a N2 atmosphere with various VOCs, including n-hexane, n-pentane, acetone, ethanol, methanol, methyl butanol, and butanol at different concentrations. Among these VOCs, the sensor displayed the most significant response to butanol, showing a sensitivity of 2.20 Hz ppm−1.
期刊介绍：
As a peer-reviewed journal for analytical sciences and technologies on the micro- and nanoscale, Microchimica Acta has established itself as a premier forum for truly novel approaches in chemical and biochemical analysis. Coverage includes methods and devices that provide expedient solutions to the most contemporary demands in this area. Examples are point-of-care technologies, wearable (bio)sensors, in-vivo-monitoring, micro/nanomotors and materials based on synthetic biology as well as biomedical imaging and targeting.
