ABSTRACT:
This invention is directed to an improved exhaust gas catalyst for the combustion of gaseous waste products from internal combustion engines, particularly automobiles, and industrial stationary source engines along with a method of making the same. The exhaust gas catalyst comprises a substantially pure alpha-alumina carrier and at least one noble metal selected from platinum, palladium and mixtures thereof, and has excellent stability over long-term use.
