Bhushan S. Pardeshi, Vasant G. Wagh, Arun V. Patil


The industrial advancement increased the various types of pollution, among them air pollution is major issue now a day’s. For air quality monitoring, different types of hazardous gas pollutant detection is essential. As a result, gas sensors are the subject of extensive investigation by scientists around the globe. Due to its unique electrical, chemical and physical properties of niobium oxide has been acclaimed as a remarkable gas detection material. Niobium oxide (Nb2O5) is utilized as sensitive materials in the construction of gas sensors based on resistivity variation measurements. Due to the fact that certain materials are gas sensitive. We described the detecting method of an undoped and doped Nb2O5 thick and thin film gas sensor for a number of oxidising and reducing gases in the current study. Furthermore, discussed how dopant and other factors affect gas sensors performance. This paper covers the advances in the research of Nb2O5 based gas sensors.
