NO2 gas sensing properties of MWCNTs/NiO nanocomposite


This study explores the influence of nickel oxide (NiO) nanoparticles on the nitrogen dioxide (NO2) gas-sensing properties of multi-walled carbon nanotubes (MWCNTs). Initially, MWCNTs functionalized with oxygen-containing groups exhibited modest sensitivity to NO2 gas, and insignificant change in resistance was observed when exposed to other oxidizing and reducing gases. Following the decoration of functionalized MWCNTs (f-MWCNTs) with NiO nanoparticles, significant enhancement in NO2 sensing responses was achieved at room temperature. The study highlights improved selectivity and elucidates the catalytic role of NiO nanoparticles in the gas-sensing mechanisms of these structures. It was found that although the sensitivity to NO2 gas increases with increasing NiO nanoparticle concentration, the mechanism of sensitivity does not change.

Keywords: nickel oxide, f-MWCNTs/NiO, sensor, NO2 gas, catalytic.
