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.
