Preparation and catalytic performance of MnOx/TiO2-ZrO2 catalysts used for the selective catalytic reduction of NO at low temperature
|
Abstract:
A series of TiO2-ZrO2 supported manganese oxide catalysts were prepared by an incipient wet impregnation method for the low temperature Selective Catalytic Reduction (SCR) of NO with NH3 as a reductant. The TiO2-ZrO2 mixed oxide support was prepared by coprecipitation. Nitrogen adsorption, XRD and TG-DSC were conducted to probe the microscopic properties of the catalysts. The results showed that MnO2 existed in a well-dispersed state at 5%.Mn on TiO2-ZrO2, but when the Mn loading was 10% and 15%, MnO2 exist...
