New mixed-oxide catalysts shown as viable substitute for platinum catalysts for diesel exhaust aftertreatment

Green Car Congress

Under laboratory-simulated diesel exhaust conditions, this mixed-phase oxide material was superior to Pt in terms of cost, thermal durability, and catalytic activity for NO oxidation. Diesel engines are attractive because of their higher fuel efficiency than gasoline engines. Wang et al., Click to enlarge. CO 2 + 2NO, NO 2 + C?CO
