今天給大家分享的是2015年4月份 《Catalysis Communications》上發(fā)表的一篇名為：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.
