Gas sensors based on multi-walled carbon nanotube (MWCNT) for detecting gaseous molecules of ammoniac (NH3) were developed and investigated. MWCNT film was grown directly by chemical vapor deposition (CVD) method on Pt electrodes to fabricate sensor device. The CNT based – gas sensor is shown sensitively and selectively to NH3 gas at room temperature.
