Iron oxides as addtive over MnOx/PG-AC catalysts for low temperature selective catalytic reduction

  • Fund Project:
  • 摘要: 采用等体积浸渍法制备MnOx/PG-AC、MnOx-FeOy/PG-AC催化剂,并通过X射线衍射(XRD)、X射线光电能谱(XPS)及场发射扫描(FESEM)等表征手段分析了Fe的掺杂对催化剂低温脱硝活性的影响.分析表明,助剂Fe的加入促进活性组分锰氧化物具有更好的分散性,为催化剂提供了更多的催化活性位点,同时助剂Fe的掺杂明显调控了活性组分Mn4+/Mn3+的价态比.一定量Fe的掺杂显著提高了催化剂的低温选择性催化还原(SCR)性能.当Fe/Mn的物质的量之比为0.8时,MnOx-FeOy/PG-AC/300 ℃催化剂表现出最佳的低温SCR脱硝活性.
