Catalyst(s) for the oxidation of NO to NO2 using O2 as the oxidant, will be developed in this proposed study. These catalyst(s) will be used in air pollution control systems to treat flue gas resulting from stationary sources, including coal-fired electrical utility boilers. By converting NO in flue gas into NO2 simultaneous removal of SO2 and NO2 from the flue gas can be accomplished. The targeted catalysts will be very active and stable for NO oxidation to NO2 but inactive for conversion of SO2 to SO3.

Titanates of iron, cobalt, zinc, nickel, and manganese will be prepared using co-precipitation methods. These titanates will be used either as catalysts or supports for catalyst preparations. Supported metal oxide catalysts will be prepared using one of the oxides of iron, manganese, cobalt, zinc, or nickel as the active component or either TiO2 or metal titanates as the support. With either TiO2 or metal titanates as the support, rather than Al2O3, the stability of these catalysts will be improved against poisoning by SO2 present in the flue gas. The catalysts prepared will be tested on their ability to oxidize NO to NO2 with oxygen in flue gas.
