NO conversion versus ramp-up and ramp-down temperatures for MnCe-7:1 (?), 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. SmMn 2 O 5 (?), GdSrCeMn 7 O 14.83 (?), and Pt (?). Click to enlarge.
