摘要：
A catalytic converter for treating exhaust gas from an internal combustion engine containing a catalyst characterized by having platinum or a platinum alloy dispersed predominantly on the exterior surface of molecular sieve crystals. Also provided is a catalyst for such a converter and processes for manufacture of such catalyst. In addition, methods for treating exhaust gas from an internal combustion engine to reduce the amounts of hydrocarbon, carbon monoxide and nitrogen oxides emitted to the atmosphere are included.
