Nanostructured Gas Sensors: the State of the Art and Perspectives for Research
The analysis of the progress in the field of the resistive gas sensors elaboration is carried out. Particularly, the novel nanoarchitectures that allow to essentially increase the sensors operating characteristics are described. As it is shown, high sensitivity, fast response, short recovery time, a considerable number of detected gases, low detection limit (about 1 ppm), reliability, compactness, relative simplicity of fabrication and low cost can be achieved due to nanostructured resistive gas sensors using.
