Washcoated catalysts on honeycomb substrates are widely used as automotive catalysts, and it is well known that their catalytic performance is limited by gas transport resistance. In order to reduce the gas transport resistance, understanding the relationship between gas transport and pore properties is essential. Since a washcoat layer consists of porous metal oxide particles (e.g., Al2O3), the washcoat layer has two types of pores: primary pores, which are located inside the porous metal… CONTINUE READING
