description The present disclosure provides a three-way conversion (TWC) catalyst composition suitable for at least partial conversion of gaseous hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (NOx). Generally, the catalyst composition comprises a platinum group metal component impregnated into a porous refractory oxide support, wherein the porous refractory oxide support has an average pore radius ranging from about 250 Å to about 5,000 Å, a total intrusion volume of at least about 1.8 ml/g, and a porosity of at least about 80%.
