Gas catalysts comprising porous wall honeycombs

Of the invention embodiment claims a catalyst the catalyst can be used for processing used for the contaminant in the air flow of the catalytic converter in. In one embodiment the catalyst comprises a base the base bottom has excesses one of the multi-hole wall elements defined axial direction of the closed passage of the said porous wall element on the inlet end and exit end of extending between. The coating ions the base located on the wall of the hole of the wall elements the surface of the invention claims a coating layer after being coated with porous rough the quality of the passage is basically does not form strip.
