Abstract: A process for depositing uniform, pure, high-surface-area metal oxide coatings on porous support structures is disclosed. The process comprises the impregnation of the support structure with an aqueous ionic solution of a selected metal followed by treatment of the impregnated support structure with ammonia or ammonia alkaline solutions to cause the in situ precipitation on the support structure of a hydrated metal oxide coating. Such metal oxide coatings are useful as catalysts or catalyst supports.

Abstract: A process for depositing a noble metal catalyst on an oxide support material comprising contacting the support material with an alkaline solution of complex noble metal-amine cations under prescribed pH conditions is disclosed. The process is particularly suitable for depositing catalysts on monolithic honeycomb support structures because the catalyst dispersions produced thereby are extremely uniform on the interior channel walls of the structure.

Abstract: Catalytic devices employing novel multiple-layer support coatings in combination with known base and noble metal catalysts are described. The devices are generally useful as supported catalyst systems and particularly suitable for use in the treatment of automotive exhaust and other waste gases. The multiple-layer support coatings typically comprise a base oxide layer composed of alumina, silica or mixtures thereof and at least one covering layer of a different composition composed of an oxide selected from the group consisting of silica, titania, zirconia, tin oxide and manganese oxide; these multiple coatings are found to enhance and/or stabilize the activity of known catalysts to a degree not demonstrated by either single-oxide or mixed-oxide support coatings used in the prior art. Also disclosed are novel deposition methods, generally useful in the deposition of the coatings of the present invention, comprising the alkoxide impregnation of a support structure and the subsequent in situ hydrolysis of the alkoxide to form an adherent hydrous oxide coating.
