Abstract
Sensors and methods for detecting combustible gases in a gas mixture are disclosed based on combustion catalyst compositions comprising an amount of a precious metal supported on an ion-exchangeable alkali metal titanate substrate. The sensors and methods are particularly useful for measuring the concentration of combustible gases in low temperature and high humidity conditions. Advantageously, certain embodiments can selectively measure the concentration of select species (e.g. ethylene).
