On account of the selective catalytic oxidation of NO in flue gas

the characteristics and progress of NO catalytic oxidation using activated carbons

molecular sieves

noble metal and metal oxide catalysts are described

on the basis of catalytic mechanism

catalytic activity

anti-sulfur-corrosion and anti-steam-corrosion performance. The research on activated carbons mainly focuses on the material modification and new material preparation. Studies on the molecular sieves put emphasis on improving the activity of catalytic oxidation reactions in a broad temperature range. Although the noble metal catalysts possess good catalytic activity

the high cost of materials have restricted their industrial application. Using the metal oxide catalyst is one of the most industrial applicable NO catalytic oxidation method owing to their high catalytic activity

relatively low price and tunable properties.
