Pollution control catalyst with mutual protective distributed-active-combinations each including noble-metal-atoms stably structured and protected therein |
摘要 |
An exhaust gas catalyst for reducing the pollutant release containing in the exhaust gas. The catalyst includes a primary-core support. The catalyst also includes a distributed-catalytically-active multi-combination catalyst structure formed on the primary core support. The multi-combination catalyst structure includes an outermost gas-contact combination which includes atoms of metals selected from platinum group atomically immersed in the micro-space between a plurality of crystalline structures of composite oxides of a plurality of catalytically active metals and intimately attached to and protected by the crystalline structures in a protective inner combination.
