每周分享：Synergistic catalysis effect of Mn-promoted BaAl2O4 catalysts on catalytic performance for soot combustion

今天给大家分享的是2015年9月份《Catalysis Communications》上发表的一篇名为：Synergistic catalysis effect of Mn-promoted BaAl2O4 catalysts on catalytic performance for soot combustion

文章摘要如下：

A series of Mn-promoted BaAl2O4 catalysts were developed for catalytic soot combustion. These catalysts were characterized using XRD, BET, H2-TPR, O2-TPD, and in-situ DRIFTS. The results showed that an optimized combustion catalyst should accommodate barium and manganese with proper balance to promote soot combustion. A synergistic mechanism was suggested to explain the synergistic effect of manganese and barium: NO was trapped mainly as nitrites by barium, while the generated nitrites further transformed to nitrates facilitated by manganese, which finally oxidized soot into CO2.
