Özet
In this study, a two-dimensional cF8 phase silicene and a Polyaniline (PANI):cF8 Silicene nanocomposite were prepared. PANI:cF8 Silicene nanocomposite-based sensor was tested against nitrogen dioxide (NO2), ammonia (NH3), formaldehyde (CH2O), ethanol (C2H5OH), methanol (CH3OH), acetone (C3H6O), chloroform (CHCl3), and hexane (C6H14) in a 1–100 part per million (ppm) range with N2 carrier gas at 25 °C. PANI:cF8 Silicene nanocomposite-based sensor showed the highest sensitivity (93.4%) against nitrogen dioxide and achieved the lowest detection limit (LOD) of 0.85 ppm. PANI:cF8 Silicene nanocomposite-based sensor detected ammonia gas with a sensitivity of 74.3%, formaldehyde with a sensitivity of 67.1%, and ethanol with a sensitivity of 61.2%, higher than the PANI-based sensor. Since silicene increases the surface area of PANI, gas adsorption is increased, detection is accelerated, and recovery time is shortened. This study demonstrated that silicene improved the gas sensor performance of PANI. PANI:cF8 Silicene based sensor is a potential candidate as an environmental monitoring sensor.
