Gas sensors are widely applied to monitor combustible and harmful gases which can be detrimental to safety, health and environment. SnO2, a wide gap semiconductor, is the most promising gas sensor material because of high chemical stability and low fabrication cost[1]. While due to the drawbacks of SnO2 working as gas sensing material, such as low selectivity and high working temperature, doping by noble or transition metals is a particularly efficient way to improve its sensing properties[2]. SnO2 doped by antimony (SnO2/Sb) is a typical n-type oxide material, which has high electrical conductivity and thermal stability.

Abstract
Gas sensors are widely applied to monitor combustible and harmful gases which can be detrimental to safety, health and environment. SnO2, a wide gap semiconductor, is the most promising gas sensor material because of high chemical stability and low fabrication cost[1]. While due to the drawbacks of SnO2 working as gas sensing material, such as low selectivity and high working temperature, doping by noble or transition metals is a particularly efficient way to improve its sensing properties[2]. SnO2 doped by antimony (SnO2/Sb) is a typical n-type oxide material, which has high electrical conductivity and thermal stability.File in questo prodotto:
