Abstract
The present invention discloses metallic fiber boards having catalytic functionality and processes for producing the same. The boards are formed from a mesh of metallic fibers, each fiber having a first layer of an oxide and a second layer of a porous oxide. A catalyst, either disposed on the surface of the second layer, or dispersed within the second layer, provides catalytic functionality to the fiber board. The first layer is produced by thermal oxidation of the metallic fibers, while the second layer and catalyst are produced by thermal decomposition of precursor materials applied to the fiber board while in solution, typically as a spray of atomized droplets. The resulting boards are used to catalyze the combustion of hydrocarbons, especially methane, and particularly in household boilers.
