今天给大家分享的是2015年4月份 《catalysis communications》上发表的一篇名为：enhanced activity of mn_xw_0.05ti_0.95 − xo_2 − δ for selective catalytic reduction of no_x with ammonia by self-propagating high-temperature synthesis

文章摘要如下：

a series of tio₂ supported mnwo_x catalysts mn_xw_0.05ti_0.95 − xo_2 − δ (x = 0.05, 0.1, 0.15) were synthesized by solution combustion method. the mn_0.10w_0.05ti_0.85o_2 − δ catalyst showed highest activity in nh₃-scr reaction within a broad temperature range of 200 °c–400 °c. xrd and tem results indicate that the active mn and w species are highly dispersed over tio₂ support in the form of nanoparticles (4–7 nm). the tem and h₂-tpr results also suggest that a mnwo_x phase has been formed on the tio₂, which is beneficial for the activity of the mn_xw_0.05ti_0.95 − xo_2 − δ catalysts in the high temperature range of 280 °c–400 °c.
