Abstract

The removal of nitrogen oxides has received much interest because of its environmental importance recently. Highly active nanorod selective catalytic reduction (SCR) deNOx catalysts composed of amorphous manganese oxides on crystalline anatase TiO2 have been prepared by template method. The sample was characterized by BET, XRD, HRTEM and EDS. The results showed that the catalyst had superior low temperature activity and the NOx conversion was nearly 100 % at 200 ºC. From the microstructure characterization, it could be known that the shape of nanorod was contributed to the dispersion of the manganese oxides. Due to better distributing of the manganese oxides, the catalyst performed catalytic activity very well.
