SEMICONDUCTOR MATERIALS Ce-SnO2/Sb2O5 AND Pd-SnO2/Sb2O5 FOR CREATING SENSITIVE ELEMENTS OF SENSORS FOR HYDROGEN

Materials based on tin dioxide doped with antimony with additions of cerium and palladium are synthesized in order to create highly sensitive and fast-responding semiconductor sensors for hydrogen. It is shown that introduction of Ce and Pd into SnO 2 /Sb 2 O 5 increases the response of the sensor t...

Description
Summary:Materials based on tin dioxide doped with antimony with additions of cerium and palladium are synthesized in order to create highly sensitive and fast-responding semiconductor sensors for hydrogen. It is shown that introduction of Ce and Pd into SnO 2 /Sb 2 O 5 increases the response of the sensor to microconcentrations of H 2 (40 ppm). The fundamental possibility of using the developed materials to create the sensitive element of a chromatographic detector is established on the basis of the electric resistance of the sensors in air, their sensitivity to H 2 , fast response time, and the range of measured hydrogen concentrations.
