【Abstract】 As a new denitrification technology,selective catalytic oxidation(SCO) has been widely applied in industry. In view of the characteristics of nitrogen oxides in flue gas, the research progress of molecular sieves, activated carbon, activated carbon fibers, metal oxides and noble metal catalysts for catalytic oxidation of NO was reviewed in terms of steam resistance, sulfur resistance and catalytic activity. Among them, molecular sieve catalysts are the most promising catalysts for the catalytic oxidation of NO because of their excellent water vapor resistance, sulfur resistance and high catalytic efficiency.更多还原
