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 Доп.точки доступа: Podval'naya, N.
