PURPOSE:To prevent the peeling of the title catalyst and to raise the water resistance, strength, etc., by depositing a catalyst mixed with a heat-resistant fibrous substance on the whole surface of a metallic substrate having many open cells to form the plate-shaped catalyst. CONSTITUTION:Metallic fine particles 8 resulting from the molten metallic droplets of SUS 304 are deposited and grown on a substrate 4a of SUS 304 to form a metallicon layer, and ultra-fine metallic particles 10 resulting from 10mu-grade ultra-fine metallic droplets are further deposited on the irregularly roughened surface. Accordingly, when the mixture of catalyst and heat-resistant fibers 11 is deposited on the substrate 4a, the fibers 11 are caught by the ultra- fine metallic particles 10, the fibers 11 and the catalyst are integrated, the material is solidified in a fine open cell 9 and strengthened, and hence the material never slips out from the cell. Since the cell is irregularly shaped, the catalyst layer is firmly held. |
