摘要

在此，我们报告了一种基于金属有机框架（MOF）的传感器的制作过程，该传感器采用 NOTT-300（Al）MOF 薄膜作为传感层沉积在互斥电容电极（IDE）上，并将其用于室温下二氧化氮（NO2）的检测。对制作的基于 MOF 的传感器进行了测试，结果表明它对浓度低至 250 ppb 的二氧化氮具有显著的检测灵敏度，检测下限约为 4.0 ppb。此外，NOTT-300（Al）MOF 传感器还显示出出色的二氧化氮传感稳定性，以及对二氧化氮和其他常见气体（如 CO2 和 H2O）的理想检测选择性。

The deployment of an NOTT-300 (Al) MOF thin film as a NO2 capacitive sensor under ambient conditions†

Herein we report on the fabrication of a metal–organic framework (MOF)-based sensor using an NOTT-300 (Al) MOF thin film, deposited as a sensing layer on an interdigitated capacitive electrode (IDE), and deploy it for the detection of nitrogen dioxide (NO₂) at room temperature. The fabricated MOF-based sensor was tested and it demonstrated a significant detection sensitivity for NO₂ with concentrations down to 250 ppb, with a lower detection limit around 4.0 ppb. The NOTT-300 (Al) MOF sensor also displayed an outstanding NO₂ sensing stability and a highly desirable detection selectivity towards NO₂vs. other common gases such CO₂ and H₂O as well.
