Abstract
Accordingly, there is provided a catalytic membrane comprising a porous substrate having a first surface and a second surface. The substrate has micropores, for example, pores ranging from about 10 .ANG. to about 2000 .ANG. in diameter, at least in a region extending from the first surface toward the second surface for a preselected distance. Preferably, the preselected distance will be sufficient to provide a measurable resistance to the flow of a fluid, such as a gas, through the micropores. A catalyst is deposited at least on the first surface of the substrate, although optionally, the catalyst is deposited on the substrate in the micorpore region. A transport layer is provided on the first surface of the substrate, including any catalyst on the first surface.
