Facile Synthesis of 2D-HfS2 Flakes for \mu -IDE-Based Methanol Sensor: Fast Detection at Room Temperature
A new and astonishing resistive gas sensor based on Al _{\mu}-{\text {IDE}} /HfS 2 , synthesized by chemical route, has been developed for precise detection of methanol vapor at room temperature. A high sensitivity of 1.29 has been found at room temperature with the exposure of 500 ppm of methanol v...

| description | A new and astonishing resistive gas sensor based on Al _{\mu}-{\text {IDE}} /HfS 2 , synthesized by chemical route, has been developed for precise detection of methanol vapor at room temperature. A high sensitivity of 1.29 has been found at room temperature with the exposure of 500 ppm of methanol vapor at an operating bias of 1 V. Sensitivity has been obtained from transient response analysis. Most importantly, very fast response/recovery characteristics with good baseline restoration have been witnessed. The response time and recovery time have been recorded in the range of ~12.12 s to ~21.14 s and ~23.72 s to ~39 s. Cross-sensitivity with other interfering species has also been studied. A comprehensive justification, including Langmuir adsorption-desorption isotherm for appreciable sensing response, has also been delineated. |
