文章摘要如下9/p>
A series of TiO2supported MnWOxcatalysts MnxW0.05Ti0.95 ?nbsp;xO2 ?nbsp;δ(x = 0.05, 0.1, 0.15) were synthesized by solution combustion method. The Mn0.10W0.05Ti0.85O2 ?nbsp;δcatalyst showed highest activity in NH3-SCR reaction within a broad temperature range of 200 °C?00 °C. XRD and TEM results indicate that the active Mn and W species are highly dispersed over TiO2support in the form of nanoparticles (4? nm). The TEM and H2-TPR results also suggest that a MnWOxphase has been formed on the TiO2, which is beneficial for the activity of the MnxW0.05Ti0.95 ?nbsp;xO2 ?nbsp;δcatalysts in the high temperature range of 280 °C?00 °C.
