Results of studies on the suitability of base metal oxides for auto pollutant control are reported. Much data is available in the literature concerning the catalytic activity of base metal oxides when used to oxidize CO and hydrocarbons. Active oxides and mixtures of oxides have been identified by experiment. The best base metal oxide catalysts that have been developed and tested for automobile exhaust purification service have shown a disadvantage when compared to present production noble metal catalysts, principally because of their sensitivity to sulfur deactivation, their lower catalytic activity and thermal stability, and increased sensitivity to lead deactivation at temperatures above the normal operating temperatures. In view of the stringent emission standards and the desire to use the most efficient catalyst in order to meet fuel economy standards, it appears that the catalyst of choice as of this time will continue to contain noble metals.
