The sulfur tolerance of the perovskite was significantly improved by the addition of palladium particles, and the character of this tolerance will be a strong function of the chemistry of sulfur. Our study also compares the NO oxidation rates and turnover frequencies of perovskite catalysts and platinum on the surface.
