| 제목 | Low-temperatureNH3-SCR of V2O5/M-TiO2 catalystsvia transition metal modification |
| 초록 | The vanadium oxide-based catalyst hasgood activity during low-temperature NH3-SCR reaction. However, the presenceof SO2 and H2O from flue gas leads to catalyticdeactivation due to the formation of ammonium bisulfate. The V2O5/M-TiO2catalysts via transition metal (Mn, Ce, Mo, Ni and Zr) modification wereinvestigated by influencing SO2 and H2O durability test. TheTiO2 surface modification improved the low-temperature NH3-SCRactivity and SO2-poisoning resistance due to the increased acidsites and weakened adsorption of NH3.Acknowledgments This work was supportedby the Technology Innovation Program (20005690, Development ofthree-dimensional metal structured De-NOx catalyst) funded by the Ministry ofTrade, Industry & Energy (MOTIE, Korea). |
