 Abstract
The effect of Pt addition over catalyst supported on PRO-66 was investigated for NO reduction in order to develop the catalytic filter working at low temperature. Catalytic filters, , were prepared by co-impregnation of Pt, V, and W precursors on -coated ceramic filter named PRD (PRD-66). Titania was coated onto the pore surface of the ceramic filter using a vacuum aided-dip coating method. The Pt-loaded catalytic filter shifted the optimum working temperature from (for the catalytic filter without Pt addition) to , reducing 700 ppm NO to achieve the slip concentration($N_x\;
