CO催化氧化消除在环保、氢燃料电池等许多领域具有重要应用,其催化剂活性成分可以使用单组分及多组分的贵金属、非贵金属、金属氧化物、复合氧化物等。非贵金属活性成分的使用对降低催化剂的成本具有重要意义。从催化剂活性成分的角度来审视不同催化剂的催化性能和构效关系,综述了CO催化氧化催化剂的研究现状。

Catalytic oxidation of CO (COC)has been widely used in many fields such as environmental protec-tion and H2 fuel cell.Single component and multy components noble metal,non-precious metal,metal oxide and mixed oxide can be used as the active components of the catalysts for COC.The use of non-precious metal active com-ponents is of great importance for the cost reduction of COC catalysts.In this review,the different active components of the COC catalysts as well as their catalytic performance are discussed.
