Abstract

Soot, often referred to as black carbon emitted from diesel engines, is not only a particulate matter pollutant but also a light-absorbing agent that may affect global climate, but can be effectively controlled using a catalytic diesel particulate filter (DPF). A new YBaCo4O7+delta-type oxygen storage material is reported as an effective catalyst for soot combustion. Isotopic isothermal reactions demonstrate the activation of gaseous oxygen and subsequent oxygen storage and reaction/desorption during an oxidation process. High activity and structural stability are achieved by the substitution of Co with Al and Ga to form YBa(Co0.85Al0.075Ga0.075)(4)O7+delta. The specific rates at 300 degrees C of YBaCo4O7+delta and YBa(Co0.85Al0.075Ga0.075)(4)O7+delta, normalized by surface areas, are an order of magnitude higher than those of CeO2-based oxides. This kind of oxygen-storage material acts as an oxygen pool, which ensures that the accumulated soot on a DPF can be promptly combusted.
