A highly effective catalyst of V/W-Fe/TiO2 for low-temperature NH3-SCR catalyst: Promotional roles of iron oxide in V based catalyst |
| 초록 |
To remove nitrogen oxide from exhaust gas with cost effective process, the low temperature NH3-SCR has been widely studied, those of the main obstacle for development is their low denitrification efficiency. This research focuses on the effect of incorporation of iron as a promoter in V-based catalysts that also introduced tungsten. The catalytic activity was evaluated over a wide temperature range between 160-300 ℃, the catalytic characterization was also comprehensively investigated. as a result, the 0.5 wt% of iron doped catalyst show about 8 % of improved catalytic activity, which of iron oxide induce highly dispersion effect of active metals and effectively form Fe2O3 and generated Fe3+ state on the catalyst. |
