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 SnO2/Sb2O5 increases the response of the sensor to microconcentrations of H2 (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 H2, fast response time, and the range of measured hydrogen concentrations.
