摘要：
The gas-sensing properties of cubic nickel-zinc stannates Zn2-xNixSnO4(with x = 0, 0.8) prepared by self-propagating high-temperature synthesis (SHS) are reported. This is the first report of using such 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 in the case of the cubic nickelzinc stannates with excellent selectivity towards ethanol. It was found that a response of 9 towards 20 ethanol could be obtained, more than twice the response to other environmentally important gases that were tested.
