Abstract
A method of producing monolith catalysts for catalysts to be used in a measure to purify the exhaust gases of a vehicle, in which, in a process of producing alumina slurry liquid, the dispersibility of the alumina particles in the slurry liquid is improved by the use of water, aluminium-nitrate powder instead of acid, alkali to allow the slurry liquid to be uniformly adhered on the surface of the dipped carrier, thereby to prevent the alumina coat layer from coming off in the high temperature.
