ABSTRACT:
A sensor for determining the concentration of a gaseous component of interest is disclosed which comprises a sensing element comprising an inorganic crystalline composition including at least one metal component in an amount effective to provide a signal related to the concentration of the gaseous component of interest, the inorganic crystalline composition having been grown, or derived from a material grown, by crystal growth upon at least a portion of the surface of an inorganic oxide composition to form a composite with at least two substantially contiguous phases which exhibit at least one of a distinct compositional heterogeneity and a distinct structural heterogeneity of one phase to the other; and processing means to process the signal and provide a basis for determining the concentration of the gaseous component of interest.
