| Abstract: | Selective catalytic reduction of NOx with NH3(NH3-SCR) is the main technology to remove NOx from coal-fired power plants and diesel exhaust.The progress in cerium oxide-based catalysts for NH3-SCR was reviewed.The effects of different supports,preparation methods and doping elements on catalytic activity and sulfur resistance were analyzed.The reaction mechanisms of NH3-SCR and the activation mechanism of NH3 and NO on cerium oxide-based catalysts were discussed in detail.The development trends of cerium oxide-based catalysts for selective catalytic reduction of NOx with NH3 were outlined. |
