説明

<jats:title>Abstract</jats:title><jats:p>Herein we report the fabrication of an advanced sensor for the detection of hydrogen sulfide (H<jats:sub>2</jats:sub>S) at room temperature, using thin films of rare‐earth metal (RE)‐based metal–organic framework (MOF) with underlying <jats:bold>fcu</jats:bold> topology. This unique MOF‐based sensor is made via the in situ growth of fumarate‐based <jats:bold>fcu</jats:bold>‐MOF (fum‐<jats:bold>fcu</jats:bold>‐MOF) thin film on a capacitive interdigitated electrode. The sensor showed a remarkable detection sensitivity for H<jats:sub>2</jats:sub>S at concentrations down to 100 ppb, with the lower detection limit around 5 ppb. The fum‐<jats:bold>fcu</jats:bold>‐MOF sensor exhibits a highly desirable detection selectivity towards H<jats:sub>2</jats:sub>S vs. CH<jats:sub>4</jats:sub>, NO<jats:sub>2</jats:sub>, H<jats:sub>2</jats:sub>, and C<jats:sub>7</jats:sub>H<jats:sub>8</jats:sub> as well as an outstanding H<jats:sub>2</jats:sub>S sensing stability as compared to other reported MOFs.</jats:p>
