Highly sensitive and selective SO₂ MOF sensor: the integration of MFM-300 MOF as a sensitive layer on a capacitive interdigitated electrode

This work reports on the fabrication of an advanced capacitive sensor based on a MFM-300 (In) MOF for the detection of SO₂ at room temperature. The sensor revealed remarkable SO₂ sensitivity down to 75 ppb with excellent stability and selectivity to other common gases/vapors.
