A series of TiO2 supported MnWOx catalysts MnxW0.05Ti0.95−xO2−δ (x=0.05, 0.1, 0.15) were synthesized by solution combustion method. The Mn0.10W0.05Ti0.85O2−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 (4–7nm). The...
The CeO 2 –WO 3 (CeW) and Mn-doped CeO 2 –WO 3 (MnCeW) catalysts were prepared by co-precipitation method. The MnCeW catalyst exhibited more activity for NO x conversion than the CeW catalyst did below 200°C. The experiment results showed that the MnCeW catalyst provided more Brønsted acid sites and higher reducibility than the CeW catalyst. Theoretical studies...
