| Abstract: | The advantages and disadvantages of oxides, precious metals, molecular sieves and bifunctional catalysts for reduction of NOx by lower hydrocarbons under lean-burn conditions have been analyzed and interpreted. The reasons of deactivation of these catalysts and the reaction mechanisms under such conditions were also discussed preliminarily and the prospects for the future works were proposed. |
