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 translation: 公开了一种在氧化物载体材料上沉积贵金属催化剂的方法，包括在规定的pH条件下使载体材料与复合贵金属 - 胺阳离子的碱性溶液接触。 该方法特别适用于在整体式蜂窝状支撑结构上沉积催化剂，因为由此产生的催化剂分散体在结构的内部通道壁上是非常均匀的。

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.
