New mixed-oxide catalysts shown as viable substitute for platinum catalysts for diesel exhaust aftertreatment
Green Car Congress
AUGUST 17, 2012
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. and octahedral coordination environments, respectively. Mullite oxides (Sm, Gd)Mn 2 O 5 have an orthorhombic structure in which Mn 3+ and and Mn 4+.
