Catalytic Removal of NO over Molybdenum Nitrides |
| 초록 |
The catalytic NO removal reactions were investigated using a series of Mo nitrides. Mo nitrides were synthesized using Mo oxide (MoO3) and ammonia gas (NH3) with different heating rates and space velocity. Various characterization techniques such as BET surface area and oxygen uptake measurements were employed to characterize different Mo nitrides synthesized in this study. Depending on the preparative conditions, BET surface areas ranged from 1 m2/gr to 28 m2/gr and oxygen uptake values varied from 0.46 ㎛ol/g to 5.41 ㎛ol/g. The Mo nitrides were found to be active for NO removal reactions. Although some Mo nitrides catalysts were exceeded by Pt/Al2O3 catalyst, the steady state reaction activities of other Mo nitrides catalysts were comparable to or even higher than that of the Pt/Al2O3 catalyst. These results implied that Mo nitrides could be one of the promising catalysts that might be able to replace platinum group noble metal catalysts in the NO removal reactions. |
