Abstract: Recently how to control and reduce NOx emission became an important content of China’s air pollution treatment. This paper briefly analyzes the NOx control methods in coal combustion，and compares the advantages and disadvantages of NOx reduction technologies，which have been interesting by researchers now. The research progress of these NO catalytic oxidations catalysts are summarized in this paper. There is less research on molecular sieves and their supported catalysts because of their low activity at low temperature. Studies on activated carbons mainly focus on their modification and the preparation of new carbon materials. Noble metals have good catalytic activity，but their high costs have restricted their industrial application. Metal oxides have been widely studied due to their high catalytic activity and distinct advantage of price. In recent years more and more researchers apply new materials and wastes to NO oxidation．
