摘要: To provide a filter catalyst in which the closure of ventilation holes by a catalytic layer is inhibited. A filter catalyst of the present invention is characterized in that it has pores of 1-20 μm in a porosity of 11% or more. The filter catalyst of the present invention has an effect of being capable of inhibiting the rise of pressure loss when sufficient particulates deposit.
