Description
Vanadium pentoxide (V2O5) is a semiconductor metal oxide material with properties that makes it suitable for gas sensing applications. These properties are strong catalytic activity, high conductivity and structural ability. Despite this, literature showed that low selectivity and high operating temperatures still limit its functionality in practice. Sulphur dioxide (SO2) is a highly toxic greenhouse gas with an unpleasant odour that is emitted primarily by the combustion of fossil fuels and volcanic eruptions. Even at concentrations as low as 5ppm, SO2 can cause serious health issues to human lives. Fabrication of highly selective and low operating temperature SO2 gas sensors are of utmost importance. The current work presents low temperature and SO2 selective gas sensor developed by doping V2O5 nanoparticles with Au using the hydrothermal synthesis method. Possible gas sensing mechanisms of the combined materials in the presence of SO2 gas are also presented.
