Abstract: A method of microfabricating a matrix of evenly distributed catalytic articles, with the matrix then being used to treat reactants in a stream of gases. The matrix is created by depositing areas of conductive material on a nonconductive base wafer or substrate, and then depositing catalyst particles in electrical communication with the conductive material so that a series of localized electrical fields can be created upon the introduction of a power source. A dielectric material surrounding the catalyst particles can be altered by increasing the applied voltage, thereby increasing the strength of the electrical field. A device so constructed is placed in a stream of gases, and the localized electrical fields alter the selectivity and the reactivity of the reactants in the stream of gases.

Abstract: A catalytic carbon formation technique in a carbon fiber substrate is disclosed. The carbon fiber substrate is first impregnated with a catalyst and is thereafter heated in an atmosphere rich in carbon and hydrogen. The catalyst is typically a Group VIII metal and may be selected from the group consisting of iron, nickel and cobalt. An incipient wetness technique for impregnating the substrate is also disclosed. A salt of the catalyst is provided in solution and void volume of the substrate is determined. The carbon fiber is then impregnated with a volume of the solution which is incrementally less that the determined void volume.
