Short summary
In this paper, we have investigated ruthenated MWCNTs/SnO2 thick-film nanocomposite sensors in the presence of propylene glycol (PG), dimethylformamide (DMF) and formaldehyde (FA) vapors in the air. The minimal PG, DMF and FA gas concentrations at which the perceptible signal is registered are 13, 5 and 115 ppm, respectively. The optimal results are shown at 200 °C operating temperature. Dependence of the response on gas concentration is linear in all cases.
