Tian et al.[6]prepared MnO2 with different morphologies using different methods(Fig.1).The experimental results showed that nanorods MnO2contributed the best denitrification effect(Table 1).High activity of the rod-like MnO2 was due to the large amount of strong acid sites,low crystallinity and more lattice oxygen.Tang et al.[7]synthesized MnO2 catalysts with different methods.It was found that MnO2prepared by solid phase method and rheological method exhibited excellent low temperature activity,and the conversion rate of NOx at 100℃was close to 100%.At the same time,the analysis showed that the amorphous state of the catalyst was the key factor for the low temperature catalytic activity.
