Abstract
A catalyst for purifying an exhaust gas includes zirconia particles, and a transition metal layer, covering at least a part of a surface of the zirconia particles in a lamellar manner. It can reduce the emission of particulate materials (i.e., P.M.), such as SOF and sulfates, because the contacting area enlarges between the transition metal layer and materials to be purified.
