“…These substrates can work in atmospheres under 300 • C with stable electric and chemical properties, which are based on the interactions of Pd-doping in Ag pastes. The required quantity of nanocomposites was evenly dispersed in the mixture of DI water and ethanol ratio of 1:1, then the paste was dispersed coated onto the interdigital area of Ag-Pd electrodes to form uniform, dense and smoothly deposited thick films by screen-printing technique [24,25]. Finally, after drying overnight, aging occurred at 120 • C for 120 h to ensure surface resistance value remained stable.…”

Acetylene (C 2 H 2 ) gas sensors were developed by synthesizing a reduced graphene oxide (rGO)-loaded SnO 2 hybrid nanocomposite via a facile two-step hydrothermal method. Morphological characterizations showed the formation of well-dispersed SnO 2 nanoparticles loaded on the rGO sheets with excellent transparency and obvious fold boundary. Structural analysis revealed good agreement with the standard crystalline phases of SnO 2 and rGO. Gas sensing characteristics of the synthesized materials were carried out in a temperature range of 100-300 • C with various concentrations of C 2 H 2 gas. At 180 • C, the SnO 2 -rGO hybrid showed preferable detection of C 2 H 2 with high sensor response (12.4 toward 50 ppm), fast response-recovery time (54 s and 23 s), limit of detection (LOD) of 1.3 ppm and good linearity, with good selectivity and long-term stability. Furthermore, the possible gas sensing mechanism of the SnO 2 -rGO nanocomposites for C 2 H 2 gas were summarized and discussed in detail. Our work indicates that the addition of rGO would be effective in enhancing the sensing properties of metal oxide-based gas sensors for C 2 H 2 and may make a contribution to the development of an excellent ppm-level gas sensor for on-line monitoring of dissolved C 2 H 2 gas in transformer oil.

“…The decrease of the operating temperature is one of the needed factors for viable gas sensors in industrial applications. Several Recently a micromachining and screen printing technique combination has been used to obtain SnO 2 based thick-film gas sensors [25,26]. The interest of this study is to improve the response of Sn-doped In 2 O 3 (ITO) thin films as regard to NH 3 gas at low operating temperature.…”

“…To decrease the power consumption of CO sensors, some attempts to use a microheater or a microhotplate have been reported in the past [4][5][6][7][8]. We have been doing research on a CO sensor based on an SnO 2 thin film that decreases the heating power consumption by using microheater technology.…”
