Tuning of CO gas sensing performance of spray pyrolyzed ZnO thin films by electron beam irradiation

Strategies to boost chemiresistive sensing performance of In2O3-based gas sensors: an overview

“…76 The inhalation of >15 ppm CO is dangerous, and the TLV of CO is 25 ppm set by the American Conference of Governmental Industrial Hygienists (ACGIH). 77 Exposure to 0.5% CO for 10 min can cause immediate death. Currently, more than 15 000 intentional CO poisoning occurs each year.…”

An 8 MeV Electron Beam Modified In:ZnO Thin Films for CO Gas Sensing towards Low Concentration

“…Selectivity is an important parameter from a practical standpoint. In our previous study [19], we studied CO sensing properties e-beam treated ZnO thin films. We also studied the CO sensing properties of unirradiated IZO thin films [24].…”

“…Some of the widely used MOS gas sensors are ZnO, WO 3 , SnO 2 , etc. [19][20][21]. In particular, ZnO is an interesting material for gas sensing due to its distinctive properties, including intrinsic n-type conductivity, chemical and thermal stability, and so on [22,23].…”

Recent Advances in ZnO-Based Carbon Monoxide Sensors: Role of Doping

“…Considered as a silent killer [ 10 , 11 ], CO is an odorless, colorless, and tasteless gas [ 11 , 12 ] produced by the incomplete combustion of fossil fuels [ 4 , 13 , 14 ], automobile exhaust emissions [ 4 , 15 , 16 , 17 ], domestic fuel burning [ 18 ], gas fires [ 14 ], agriculture product burning, volcanic activity [ 18 ], industrial exhaust emissions [ 16 ], and fault monitoring in large power equipment [ 19 ] and carbon-containing compounds, such as domestic appliances [ 4 , 14 ] and coal mines [ 7 , 20 ]. Lately, CO emissions have been increasing, owing to accidental leakage associated with technological advances in electrical appliances [ 21 ], greater environmental pollution, industrialization activities [ 18 ], and incomplete combustion of wood, crude oil, and natural gas derivatives with other pollutants [ 10 ]. Its detection and monitoring are of great interest to prevent it from going unnoticed because of its characteristics mentioned earlier [ 15 , 21 ].…”

Therefore, designing high-performance gas sensors for detecting this highly toxic gas is necessary.…”
