Silica Supported Au-CuO Catalysts for Low Temperature CO Oxidation

Au-CuO/SiO2 was investigated as a catalysts for the oxidation of CO under simulated diesel exhaust conditions.  The catalyst demonstrates low temperature activity and increased thermal stability, but its performance is inhibited by the presence of NO and C₃H₆.  Catalysts and approaches to mitigating this inhibition will be discussed.
