Honey comb structured catalyst containing noble metals

Abstract From the Canadian patent

A carrier-supported catalyst for use in the decontamination of motor exhaust gas is produced. The catalyst comprises a honey comb structure of high melting material selected from the group consisting of alumina cordierite, mullite and mixtures thereof provided with an intermediary layer of alumina as its carrier, and a nickel oxide layer and platinum deposited on said nickel oxide layer as its active ingredients. Typical of catalyst production are the following steps:, 1) alumina nickel oxide and platinum, respectively are deposited on, the honey comb structure by first heating it to 300 to 400°C and then dipping it, while hot, into the aqueous solution of the respective salts; 2) …
