Herein we report the fabrication of an advanced sensor for the detection of hydrogen sulfide (H S) at room temperature, using thin films of rare-earth metal (RE)-based metal-organic framework (MOF) with underlying fcu topology. This unique MOF-based sensor is made via the in situ growth of fumarate-based fcu-MOF (fum-fcu-MOF) thin film on a capacitive interdigitated electrode. The sensor showed a remarkable detection sensitivity for H S at concentrations down to 100 ppb, with the lower detection limit around 5 ppb. The fum-fcu-MOF sensor exhibits a highly desirable detection selectivity towards H S vs. CH , NO , H , and C H as well as an outstanding H S sensing stability as compared to other reported MOFs.
本文报告了一种使用具有 fcu 拓扑结构的稀土金属（RE）基金属有机骨架（MOF）薄膜在室温下检测硫化氢（H2S）的先进传感器的制造方法。这种基于 MOF 的独特传感器是通过在电容叉指电极上原位生长富马酸基 fcu-MOF（fum-fcu-MOF）薄膜制成的。该传感器对 H2S 的检测灵敏度非常高，浓度低至 100 ppb，检测下限约为 5 ppb。与其他报道的 MOFs 相比，fum-fcu-MOF 传感器对 H2S 与 CH4、NO、H2和 C2H4的检测具有高度理想的选择性，并且具有出色的 H2S 传感稳定性。
