Abstract

The influence of substrate on the gas sensing performance was studied, focusing on the functional groups of the cellulose substrate. For the study, three different gas sensors were fabricated by spray of Oxidized single-walled carbon nanotubes (Oxy-SWCNTs) on three types of substrates, i.e., silicon wafer, mechanically fibrillated cellulose nanofiber (MFCN), and TEMPO-oxidized cellulose nanofiber (TOCN). The morphologies and chemical structures of the cellulose nanofiber (CNF) substrates were analyzed using electron microscopy and Fourier transform infrared spectroscopy. The surface roughness and the functional group of cellulose substrates gave significant influenced on the sensing performance. The oxygen-containing functional groups of CNFs provided an additional p-doping on the Oxy-SWCNTs, as confirmed by Raman spectroscopy. Especially, TOCN withdrew electrons from the Oxy-SWCNTs owing to the high electron-withdrawing strength of the carboxylate groups. Meanwhile, MFCN had less chance to withdraw electrons because of the weak electron-withdrawing strength of the hydroxy group. As a result, the sensing performances of TOCN-based sensor showed excellent selectivity, sensitivity, and limit of detection toward electron-withdrawing gas, NO2. Based on the experimental study, a sensing mechanism of CNF-based sensor was proposed in terms of electron transfer pathways.
