Abstract
A catalyst material including a catalyst carrier including a porous alumina support and a hindrance layer on the alumina support, the hindrance layer comprising one or more barium sulfate, strontium sulfate, zirconium sulfate, and calcium sulfate is described. The catalyst carrier further includes a rare earth oxide. The catalyst material can further comprise a platinum group metal oxide. The hindrance layer may prevent the rare earth oxide from forming a complex with the support. The catalyst material is useful for methods and systems of abating pollutants from automotive exhaust gas.
