Abstract
The present invention provides a non-PGM catalyst for burning carbon soot without using a noble metal, the non-PGM catalyst comprising: a cerium-praseodymium complex oxide and an iron oxide, the cerium-praseodymium complex oxide impregnated with silver (Ag). The cerium-praseodymium complex oxide illustratively consists of 60 to 95 wt % of cerium oxide and 5 to 40 wt % of praseodymium oxide, and silver (Ag) impregnated in the complex oxide is 1.5 to 3.0 parts by weight of the total weight of the complex oxide. The iron oxide may be an oxide in a form of particles separate from the cerium-praseodymium complex oxide in which silver is impregnated, and may be 0.5 to 2 parts by weight of the total weight of the cerium praseodymium complex oxide.
