摘要：

The gas-sensing properties of nanostructured vanadium oxide doped with alkali-metal cations (M (x) V2O5 with M = Na, K, Rb, and Cs) have been studied by measuring the resistance of films as a function of analyte content using an impedance meter. The results show that the doped vanadium oxide is sensitive to hydrogen, carbon monoxide, and ammonia in the concentration ranges 0.1-80, 0.1-5, and 0.1-5 vol %, respectively. The strongest gas response is offered by Rb0.47V2O5, which is due to the smallest interlayer spacing in the structure of this nanomaterial and to its larger specific surface area.
