A special gas sensor based on mesoporous WO3 sensing electrode in medium low temperature for NO2 detection

Au-Decorated Polyaniline-ZnO Electrospun Composite Nanofiber Gas Sensors with Enhanced Response to NO2 Gas

“…Exposure to NO 2 can result in respiratory diseases, including bronchitis, pulmonary edema, pharyngeal, and asthma [3], and aggravate existing heart conditions [4]. In addition, it can cause acid rain and photochemical smog [5,6]. Further, even at low concentrations, it has negative effects on the human immune system and nervous system and can inhibit cell growth [7,8].…”

Facile preparation of Au-loaded mesoporous In2O3 nanoparticles with improved ethanol sensing performance

“…7,8 Semiconductor metal oxides (SMOs), which are promising gas-sensing materials, have been widely studied for the detection of inflammable, explosive and toxic gases thanks to their high sensitivity, easy preparation and convenient integration. [9][10][11][12][13] Numerous SMOs, such as ZnO, [14][15][16] SnO 2 , [17][18][19][20] In 2 O 3 , [21][22][23] Fe 2 O 3 , [24][25][26] TiO 2 , 27 WO 3 [28][29][30][31] etc., have been extensively used as sensing materials. Among them, In 2 O 3 has attracted a lot of attention by virtue of its merits of high surface reactivity and high carrier concentration, and has widespread applications in the areas of photonics, optics, electronics, photocatalysis and gas sensors.…”
