Gas sensing properties of multicomponent systems based on oxides of manganese, copper and yttrium
The composites based on manganese oxide (MnO2–х), copper oxide (CuO) and yttrium oxide (Y2 O3) are obtained. The gas response and selectivity of multicomponent composites to toxic and hazardous gases are found. Enhanced gas response of MnO2–х/CuO composite to hydrogen sulfide and methylcyan are...

| Summary: | The composites based on manganese oxide (MnO2–х), copper
oxide (CuO) and yttrium oxide (Y2
O3) are obtained. The gas
response and selectivity of multicomponent composites to toxic and hazardous gases are found. Enhanced gas response of
MnO2–х/CuO composite to hydrogen sulfide and methylcyan are
observed as compared with as-grown manganese oxide. Doping
of MnO2–x by yttrium oxide instead of copper oxide leads to
changes gas-sensing properties of the composite to hydrogen
sulfide, formaldehyde and sulfur dioxide. The presence of copper
and yttrium oxides in MnO2–x increases the response to ethyl
alcohol vapors. |
