摘　　要：NO_x是形成酸雨、雾霾以及光化学烟雾等环境问题的元凶之一。目前为止,如何有效地消除NO_x依然是一个值得关注的问题。众所周知,NO氧化催化剂有助于提高废气中NO_2的比例,这可以(i)提高NO_x储存/还原(NSR)催化剂的吸附性能;(ii)提高NO_x选择性催化还原(SCR)催化剂的低温活性(快速SCR反应);(iii)促进碳烟燃烧,从而使颗粒物捕集器(DPF)再生。本文主要综述了NO氧化催化剂的研究进展。Nitrogen oxides （NO） are major sources of air pollution, resulting in the haze, acid rain and photochemical smog. So far, the effective removal of NOx is still a matter of concern. It is generally known that NO oxidation helps to increase the proportion of NO2 in lean exhaust gas,which can （i） enhance the adsorption performance of NOx storage and reduction catalysts （NSR）, （ii） improve the low temperature activity of the NOx selective catalytic reduction （SCR） catalysts through fast SCR and （iii） promote soot combustion for the regeneration of the diesel particulate filter （DPF）. This article mainly reviews the research progress of NO oxidation catalysts.
