建立一种快速、可靠的硝基苯气相检测方法是非常重要的。本工作利用石英晶体微天平(QCM)平台，利用PCN-224的卟啉金属有机骨架(MOF)作为一种新型的传感材料，实现了对硝基苯蒸气的灵敏和选择性检测。此外，S的快速响应时间只有16%。同时，气敏元件的频移可以与硝基苯蒸气浓度成比例地猝灭。此外，这种基于PCN-224的传感器对硝基苯蒸气表现出极大的稳定性。这为气相中硝基苯检测在公安领域的实际应用埋下了伏笔。
It is vital to develop a quick and reliable approach for nitrobenzene in gas phase detection. In this work, the quartz crystal microbalance (QCM) platform was used to take advantage of the porphyrin-based metal-organic frameworks (MOFs) of PCN-224 as a novel sensing material for the sensitive and selective detection of nitrobenzene vapor. Besides, a quick response time of only 16 s was achieved. Meanwhile, the frequency shift in gas sensor could be proportionally quenched in correlation with the concentration of nitrobenzene vapor. Additionally, this PCN-224-based sensor demonstrated great stability to nitrobenzene vapor. This foreshadowed the huge potential of nitrobenzene detection in gas phase for practical applications in public security.
