Abstract
A filter catalyst is for purifying exhaust gases, and comprises a honeycomb structure, a catalytic layer and a fibrous layer. The honeycomb structure comprises inlet cells clogged on a downstream side of a flow of the exhaust gases, outlet cells neighboring the inlet cells, and clogged on an upstream side of the flow of the exhaust gases, and cellular walls demarcating the inlet cells and the outlet cells, and having pores. The catalytic layer is formed on a surface of the cellular walls and an inner surface of the pores, and includes a porous oxide and a catalytic ingredient loaded on the porous oxide. The fibrous layer is formed on the outermost surface of the cellular walls of the inlet cells at least, and includes entangled fibrous substances composed of a heat-resistant material. The filter catalyst inhibits the pressure loss from increasing and upgrades the oxidizing rate of PMs greatly.
