“…Among all semiconductors that can be used as sensors, the binary oxide SnO 2 is regarded as one of the most promising materials for such purpose [8][9][10][11], because it possesses some of the above desired features, like high sensitivity and chemical stability [12][13][14]. However, some other semiconductor types, with more complex crystal structures, are currently investigated, like the ones with perovskite structure: Ca Pb 1− TiO 3 , SmFeO 3 , and SrFeO 3 [15][16][17]; spinel structure: MgAl 2 O 4 , CdCr 2 O 4 , and ZnFe 2 O 4 [18][19][20]; and oxides with trirutile-type structure: CoTa 2 O 6 , NiTa 2 O 6 , and CoSb 2 O 6 [21][22][23]. Among the latter, the type-n semiconductor zinc antimonate ZnSb 2 O 6 has been extensively studied for gas sensing applications due to its high response to several toxic gases [24].…”

ZnSb2O6has been synthesized by a microwave-assisted solution method in order to test its possible application as a gas sensor. Zinc nitrate, antimony trichloride, and ethylenediamine were used as precursors and deionized water as solvent. Microwave radiation, with a power of ~350 W, was applied for solvent evaporation. The thermal decomposition of the precursors leads to the formation of ZnSb2O6at 600°C. This oxide crystallized in a tetragonal structure with cell parametersa=4.66 Å,c=9.26 Å and space groupP42/mnm. Microwires and microrods formed by nanocrystals were observed by means of scanning and transmission electron microscopies (SEM and TEM, resp.). Pellets of the oxide were tested as gas sensors in flowing atmospheres of carbon monoxide (CO) and propane (C3H8). Sensitivity increased with the gas concentration (0–300 ppm) and working temperatures (ambient, 150 and 250°C) increase. The results indicate high sensitivity of ZnSb2O6in both gases at different concentrations and operating temperatures.

“…However, amperometric sensors are also used to measure species other than those that are mobile in the electrolyte. For example, oxygen ion-conducting electrolytes, including YSZ [350][351][352][353][354][355][356] and LSGM [357][358][359][360][361], have been used in amperometric sensors for NO detection, in which case the source of oxygen for the electrolyte is NO rather than O 2 . For the amperometric measurement of a reducing species, on the other hand, oxygen can be pumped through the electrolyte to oxidize the reducing gas; consequently, YSZ has been used in amperometric sensors for measuring CO [362] and hydrocarbon gases [363,364].…”

Solid electrolytes are well suited for use in chemical sensors for high-temperature applications. The first such sensors followed from the use of solid electrolytes for thermodynamic measurements, and are based on galvanic cells, for which the open circuit voltage is related to the concentration of the mobile ionic species, or to another target species through equilibration at the electrode surface. However, sensors can also be based on nonequilibrium, but steady-state, potentials established between electrochemical reactions at the electrode. Another approach is to use the current passing through the electrolyte, rather than the voltage across the electrolyte, as the sensor signal. In this chapter we first describe the different methods for using solid electrolytes in chemical sensors, and then discuss some of the materials challenges and example applications. IntroductionMore than 50 years ago, Kiukkola and Wagner [1] demonstrated that solid electrolytes couldbeusedingalvaniccellstomeasurethethermodynamicpropertiesofoxides.Those pioneering studies subsequently led to the more practical application of solid electrolytes in chemical sensors. The ionic conduction in solid electrolytes is thermally activated and thus its rate increases with increasing temperature; consequently, solid electrolytes are well suited for high-temperature applications. On the other hand, such temperature dependencealsomeansthatsensorsbasedonsolidelectrolytescanrespondsluggishlyor may be inoperable at low temperatures. However, one of the advantages of solid-state devices, such as those based on solid electrolytes, is that they can be miniaturized [2,3].
