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

今天給大家分享的是2015年9月份《Catalysis Communications》上發(fā)表的一篇名為：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.
