A series of TiO₂supported MnWO_xcatalysts Mn_xW_0.05Ti_{0.95 �?nbsp;x}O_{2 �?nbsp;δ}(x = 0.05, 0.1, 0.15) were synthesized by solution combustion method. The Mn_0.10W_0.05Ti_0.85O_{2 �?nbsp;δ}catalyst 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 MnWO_xphase has been formed on the TiO₂, which is beneficial for the activity of the Mn_xW_0.05Ti_{0.95 �?nbsp;x}O_{2 �?nbsp;δ}catalysts in the high temperature range of 280 °C�?00 °C.
