Non-thermal plasma-assisted NOx storage and reduction on a LaMn0.9Fe0.1O3 perovskite catalyst

- LaMn0.9Fe0.1O3 perovskite catalyst was used as a LNT catalyst.
- Employing H2-plasma in rich phase to assist reduction of the stored NOx.
- High NOx conversion can be obtained at low temperatures (<300 °C).
