Beschreibung
Zusammenfassung:	A NO2 gas sensing element includes an electrolyte, a reference electrode in contact with the electrolyte, and a sensing electrode selective to NO2 in contact with the electrolyte spaced apart from the reference electrode. The NO2 selective sensing electrode includes an oxide material comprising: (1) a mixed oxide according to the formula (Mn2-u-v-wCovMgwSiO4-u)+ξ(Mn3Al2Si3O12)+δ(SiO2), wherein 0≦(u+v+w)≦2.0, 0≦ξ≦0.5, and 0≦δ≦0.1; (2) a mixed oxide according to the formula (Mn2-x-y-zCoyMgzSiO4-x)+ξ(ZnO)+δ(SiO2), wherein 0≦(u+v+w)≦2.0, 0≦ξ≦0.5, and 0≦δ≦0.1; or combinations of mixed oxides (1) and (2).
