Diesel engines have stood out for their high performance, with the disadvantage of emitting particulate matter. Diesel particulate filters (DPF) are an after-treatment system implemented to prevent their release into the atmosphere. Cordierite ceramic monoliths are currently widely used as DPFs. In order to develop systems that can be technologically applicable, the production costs of structured catalysts must necessarily be reduced. To this end, it was proposed to develop Ce and Co oxide particles in the laboratory and deposit them on stacked wire mesh and cordierite monoliths. The developed catalytic systems were evaluated for diesel soot combustion.
