• and metal-functionalized MWCNTs towards NO2, H2S, NH3 and C4H10, at the both sensor temperatures, 100 and 150 °C. The mean sensitivity of Pd-modified MWCNTs, specifically with the highest metal loading, towards NH3 and C4H10 was always higher than that of MWCNTs modified with Au NPs, at all operating
