Nano-sized oxide catalyst was coated on silicon carbide (SiC) surface and gas removal activity was compared using CO and NH3 molecules. In order to prepare coating solution nano-sized oxide (Cu-Mn oxide) particles was prepared firstly by wet-chemical process (redox precipitation), followed by homogeneous dispersion in the various dispersion media such as cellosolves, ketones, colloid silica, etc. Then the catalyst loading was carried out by dipping/spraying the coating solution onto the surface of porous SiC honeycomb. The physico-chemical properties and gas removal activity of the catalyst-loaded SiC honeycomb were discussed in detail. |
