Surface lattice oxygen (Olatt) over transition metal oxides plays a pivotal role in catalytic combustion of automobile exhaust. The insufficient Olatt activity at low temperatures, however, remains the key problem restricting its practical application. To overcome this deficiency, we activated the Olatt of mullite SmMn2O5 through the interface fabrication with spinel Co3O4. The optimized Co3O4/SmMn2O5 catalyst exhibited 90% conversion at 247 °C for the typical automobile exhaust propane combustion, 77 °C lower than the original SmMn2O5. Addit...
