Nitrogen dioxide thin film gas sensors for environmental control

摘要

Thin-film structures of inorganic and organic electron-, defectelectron-, and ion-conducting materials were optimized to detect selectively NO$-2$/ in the gas phase for environmental control applications. We present results on electronic conductance sensors based upon SnO$-2$/ and PbPc, and on potentiometric sensors based upon the solid-state electrochemical cell Ag/AgI/PbPc/C.
