Abstract

A porous ceramic structure with low pressure loss and high catalytic performance is provided. The porous ceramic structure includes a porous structure body (i.e., honeycomb structure) composed primarily of cordierite, and manganese (Mn) and tungsten (W) that are fixedly attached to the honeycomb structure. Thus, pressure loss in the porous ceramic structure can be reduced, and an NO combustion temperature in the porous ceramic structure can be lowered. In other words, the aforementioned structure of the porous ceramic structure allows the porous ceramic structure to have low pressure loss and high catalytic performance.
