Multilayer selective sensor structures based on nonstoichiometric oxides of manganese and tin

The morphology, chemical composition of nonstoichiometric manganese oxide obtained by various methods for its use as a sorbing layer are investigated. The changes in the chemical state of manganese after interaction with hydrogen sulfide vapors have been studied. The differences in the sorption mechanism for layers obtained by different technological modes are shown. The possibility of creating a test sensor structure with a sorbing layer based on manganese and tin oxides is demonstrated.
