Abstract :
The gas-sensing properties of spinel and orthorhombic ferrites (NiFe2O4, CoFe2O4 and LaFeO3 respectively) prepared by self-propagating high-temperature synthesis (SHS) are reported. This is one of the first reports of using an SHS derived powder for gas sensing applications. The gas response of the materials was investigated against a range of gases (ethanol, ammonia, propane, CO, ethane, ethene) at a variety of operating temperatures. Good gas response behavior was found with excellent selectivity towards ethanol.
