<p>PURPOSE: To produce an oxidation catalyst having superior heat resistance even at a high temp. CONSTITUTION: Oxide of an alkaline earth metal is carried on one or more kinds of oxides selected from among alumina, silica, titania and zirconia, oxide of an alkaline earth metal is carried on palladium oxide and they are mixed with a binder to prepare a slurry. A heat resistant honeycomb substrate is coated with the slurry to produce the objective oxidation catalyst.</p> |
